The InfoQ Java editorial team provides an annual summary of how they currently see the adoption of technology and emerging trends within the Java space. The focus is on Java the language, as well as related languages such as Kotlin and Scala, the Java Virtual Machine, and Java-based frameworks and utilities.
This talk will discuss these trends in more detail by the authors of the 2020 report. They will discuss trends in core Java, such as the adoption of new versions of Java and also the evolution of frameworks (web-based and otherwise) such as Quarkus and MicroProfile.

The
so
there's
three
of
us
of
the
four
that
contributed
to
this
report
and
we'll
talk
more
about
that
in
a
minute.
So
there's
there's
a
four
of
us
right
there,
ben
evans,
who's
the
lead
editor
of
the
java
q,
as
we
call
it
on
info
cue.
It's
a
you
know
it's
a
cue
dedicated
just
for
the
java
and
jvm
languages
over
there.
B
He
helps
organize
the
london
java
community
and
also
a
member
of
the
jcp
executive
committee,
ben's,
a
java
champion
three-time
java,
one
rockstar
and
has
author
of
a
couple
of
books,
the
well-grounded
java
developer
java
in
a
nutshell
and
optimizing
java.
So
he's
you
know
quite
involved.
He
is,
I
forget
his
exact
title,
but
he
works
for
a
new
relic
and
so
so,
like
I
said
we
we
always
you
know.
Ben
ben.
B
Does
all
the
approvals
of
news
items
in
in
our
you
know
in
our
java
queue
and
also
you
know
we
have
him,
do
a
final
review
before
we
publish
so
I
myself,
my
name
is
michael
redlich.
I
am
a
30
plus
year
veteran
of
exxon,
mobil
research
and
engineering
here
in
beautiful
clinton,
new
jersey,
it's
in
the
western
part
of
the
state
near
the
delaware
river,
and
I've
been
writing
for
info
cue
for
the
last
four
and
a
half
years.
B
B
B
Sure,
hey
everyone
nice
to
meet,
you
virtually
meet
you
all.
I
am
adaytatharaju,
I'm
a
tech
lead
and
principal
sc
at
oracle.
My
primary
focus
is
on
search
commerce,
information,
retrieval
and
machine
learning.
As
you
might
have
guessed,
I
am
one
of
the
editors
at
info
queue.
The
primarily
write
about
the
java,
the
occasional
aiml
and
devops
pieces
yeah.
So
that's
me
thanks.
A
Sure
my
name
is
eric
coslow,
I'm
developer
relations
for
contrast,
security
focused
on
securing
applications
that
run
on
the
jvm
from
the
inside,
using
instrumentation
to
defend
how
they're
actually
vulnerable,
rather
than
how
they're
attacked
prior
to
that.
I
was
one
of
the
product
managers
of
the
java
platform
group
in
oracle.
So
I
thought
it
was
interesting
to
join
the
info
queue
news
group.
B
Great
thank
you.
I
just
want
to
say
it's,
so
we
have
a
great
great
team.
You
know
we've
worked
together
on
a
number
of
items
and
you
know
it's
it's
a
it's
a
joy
writing
for
the
for
info
cue!
It's
it's
very
rewarding
and
I'm
sure
you
guys
feel
the
same.
So
so
at
the
bottom
you'll
see
the
url.
I
I'm
going
to
pdf
this
assuming
google
slides.
You
can
do
that.
B
B
First
of
all,
some
key
takeaways
and
we'll
look
a
little
bit
in
depth
at
growl,
vm,
quarkus,
java,
11
micro
profile,
and
I
have
some
live
demos
planned
and,
of
course,
that's
always
trouble
when
those
things
happen
so
we'll
see
how
well
or
not
so
well
that
works
out
all
right.
First,
a
disclaimer
here.
So
you
know
this
is
the
viewpoints
from
the
four
of
us,
but
that
only
tells
part
of
the
story.
B
B
If
you
guys
feel
differently
about
a
particular
viewpoint,
please
please,
please
send
us,
send
us
email.
You
can
provide
that
at
the
end,
so
yeah
we
we
look
forward
to
interacting
with
everybody.
You
know
we.
You
know
we
go
to
different
java
groups.
You
know
we
go
to
conferences
and
whatnot,
so
you
know
look
forward
to
to
working
with
all
of
you
on
that.
B
So
the
java
trends
report
is
this
is
only
the
second
year,
so
this
is
going
moving
forward.
This
will
be
an
annual
report
and
the
intent
of
this
is
to
provide
technical
leaders
in
making
good
decisions
for
mid
and
long-term
technology
investments
and
also
for
indev,
individual
developers
like
yours,
like
yourself
and
in
choosing.
You
know
where
you
would
like
to
invest
your
time
and
learning
some
of
these
new
technologies.
You
know
you
may
have
you
know
some
interest
in
learning,
you'll,
say
microprofile,
but
you're.
Not
quite
sure.
B
So
that's
that's
the
kind
of
thing-
and
this
is
you
know,
there's
a
chasm
that
you
know
transfers
over
from
early
adoption
to
more
late
adoption
and
there's
a
generic
there's,
a
generic
bell
curve
here.
So
there's
you
can
see.
The
chasm
is
what
you
have
to
overcome
for
success,
and
you
know
you
see
at
the
bottom
on
the
x-axis.
There
are
the
innovators
and
early
adopters
and
then
once
you
cross
the
chasm,
then
you
kind
of
you
know
your
technology
will
move
from
early
majority
to
late
majority.
B
B
All
right
so
this
is
these
are
the
key
takeaways
and
you
know
it's
basically.
This
has
taken
verbatim
from
from
the
report,
but
I
just
wanted
to
mention
them
at
the
beginning
and
we'll
talk
a
little
bit
more
about
that
as
well.
So
as
you
may,
as
you
may
not
be
surprised
to
hear
you
know,
cloud
deployment
and
containerization
you
know
is
huge.
Today
I
mean
you
can't
go
anywhere
without
you
know
having
an
example
using
docker
or
something
with
kubernetes
yeah.
B
You
know
so,
and
I
think
there's
there's
another
competitor
to
docker
with
jib.
I
believe,
if
I'm
not
mistaken,
so
it's
you
know
like
I
said
you
can't
go
anywhere
without
seeing
anything
about
this,
so
so
that's
the
first
thing:
growl
vm
really
has
come
on
to
this
scene,
and
you
know
for
converting.
You
know
j.
B
You
know
binaries
like
class
files
from
from
java
into
native
code
right
and
when
you
first
started
hearing
about
this
two
or
three
years
ago,
I
would
say
it's
actually
been
around
a
little
bit
longer.
This
was
something
baking
in
oracle
labs
for
a
while,
and
there
may
have
been
some
documentation
on
that.
If
you,
if
you
really
go
and
search
for
it,
but
it
really
started
to
you
know,
come
on
its
own.
B
A
Yeah,
so
with
regards
to
mandrill
one
of
the
ways
that
I
look
at
things
being
able
to
cross
the
chasm
and
become
particularly
relevant
is
when
more
than
one
group
does
them.
So
we
looked
at
growl
vm
and
that
was
available
through
oracle
labs,
where
you
could
acquire
it,
but
the
same
way
that
java
has
multiple
jres,
where
you
can
get
your
jre
from
sun
from
ibm
from
fujitsu
from
hp
from
zuul.
A
The
presence
of
mandrel
showing
up
as
an
alternative
to
grawl
vm,
that's
effectively
built
on
the
same
thing
is
a
demonstration
that
multiple
companies
are
now
involved
and
that
the
approach
is
validated
because
more
than
one
group
is
doing
it.
So
you're
certainly
welcome
to
use
grail
vm
or
you
can
use
red
hat's
mandrel
build
the
same
way
that
you
could
use
oracle,
jdk
or
red
hat
jdk
great.
B
Thank
you
yeah,
so
I
have
not
had
a
chance
to
digest
mandrel.
I
saw
your
I
printed
out
your
news
piece
here,
but
it's
better
coming
from
the
person
who
wrote
it
right
so
and
then
the
the
opposite.
You
know
also
true.
There
too
is
project
laden
could
be
an
interesting
new
direction,
but
this
is
in
its
early
stages.
B
B
B
As
a
matter
of
fact,
this
is
by
red
hat,
so
red
hat
had
wildfly
swarm
as
their
microservices
server
and
then
that
migrated
over
to
thorntail
and
then
corcus
came
along
almost
as
a
replacement.
I'd
say,
I
believe,
thorntail
exists
today
still,
but
I
have
not
seen
too
much
about
it.
In
the
past
year
or
so.
B
Being
berman,
I
understood
that
so
anyway,
yeah
so
we'll
talk
a
little
bit
about
more
quarkus
as
well
and
java
11.
You
know
basically
has
now
achieved
close
to
20
of
production
and
java
8,
making
up
the
remaining
80,
and
you
know
I
didn't
this
was
news
to
me
when
I
read
this
and
I
just
never
really
paid
attention
to
to
all
that.
There's
been
no
significant
deployments
of
the
non-lts
releases
and,
if
you
think
about
it
I
mean
thinking
about
java.
B
B
I
believe
speed
meant
they
do
a
database
similar
to
j-o-o-q
and
all
that
they,
I
think,
modulize
their
application.
So
there
may
be
a
few
people
doing
that
out
there,
and
I
have
a
graph
later
on.
I
can
show
talk
a
little
bit
about
about
more
of
this
right
here,
so
as
also
a
url
at
the
bottom
on
that
written
by
alex
bluewith.
I
think
that's
how
you
pronounce
his
name
on
a
new
relics,
jvm
report
that
was
came
out
earlier
this
year.
B
Okay,
so
this
is
the
you
know
the
the
model,
the
medical
model
here
here,
and
this
is
from
last
year,
and
this
was
july
of
last
year.
So
that's
that's.
I
mentioned
that
for
a
reason
at
the
bottom
of
the
innovators
you'll
see
java
ee
to
jakarta,
ee
and
jakarta.
Ee-8
was
released
in
september
of
last
year
and,
as
you
may
have
heard,
jakarta
ee9
was
just
released
earlier
this
week.
B
So
corkus,
as
you
see,
was
in
the
innovators
section
in
that
tail
of
the
bell
curve,
and
then,
of
course,
you
know,
java,
12,
13
and
beyond
early
adopters.
You
know
java
11
in
that
space.
You
know,
as
you
saw
before,
is
20
of
deployments
in
production
and
also
to
the
non-hotspot
jvm.
So
open
j9
by
ibm
has
been
around
a
bit.
Growl
is
it's
part
of
grav
vm?
B
That's
the
hotspot
jvm
or
I'm
sorry,
the
jvm
for
for
that
helidon
is
a
newer
framework
that
was
released
to
just
about
two
years
ago.
I've
actually
had
a
chance
to
study
helidon.
I
actually
like
it.
It's
quite
good
and
I've
written
some
stuff
on
there.
If
you
want
to
take
a
look
at
info
cue
and
do
a
search
verdex,
I
you
know
it's
listed
here
as
a
niche
uptake,
I
haven't
seen
too
much
about
it.
I
don't
know
uday
or
eric.
Can
you
say
something
about
verdicts?
A
Yeah
vertex
was
a
bit
of
a
reactive
framework
or
you
had
to
code
a
lot
of
things,
so
you
basically
had
to.
From
my
perspective,
you
had
to
write
a
lot
of
everything
and
that
made
it
interesting
for
people
who
wanted
to
do
it
at
that
level,
but
most
of
what
I've
seen
from
vertex
is
it
being
folded
into
other
things.
Okay,.
B
Yeah,
I
think,
behind
the
scenes,
quarkus
also
supports
vertex
for
its
reactive
framework
yeah.
Yes,
it's
built
on
top
of
that,
but
yeah
it's
an
interesting
project,
yeah
I've,
I've
messed
with
it
about
three
or
four
years
ago,
at
least
at
one
of
the
conferences
I
attempted,
but
that
was
about
the
extent
of
it.
Lego
is
an
interesting.
This
is
a
framework
by
lightbend
microservices
framework,
and
I
know
about
three
years
ago
I
was
at
a
conference
and
interviewed
somebody
who
worked
full
look.
B
You
know
for
lightbend
and
talked
about
look
home.
You
know
it's.
I
haven't
seen
too
much
about
it,
I'm
not
sure.
Where
really
you
know
personally
myself,
I
have
not
seen
too
much
buzz
about
it,
but
but
it's
there,
you
know
here
in
early
adopters
microprofile,
as
you
as
you
may
well
know,
is
been
around
since
2016.
B
they're
on
the
verge
of
releasing
4.0
and
we'll
talk
more
about
that
in
a
little
bit
later
on
and
micronaut
actually
came
out
about
maybe
six
months
before
heladon,
and
this
is
another.
You
know
framework
that
was
released
by
object,
computing
inc,
and
this
was
graham
brosher,
who
was
involved
in
grails,
came
up
with
that
and
interestingly,
oh,
he
actually
went
over
to
oracle
earlier
this
year
and
I
failed
to
mention
helodon
was
released
by
oracle.
B
So
on
the
other
side,
now
you
know
you
have
you
know
kotlin,
j,
ruby,
reactive
java.
So
again
this
is
still
last
year's
right.
So
interesting
about
this
is
that
the
micronaut
family
of
apis
has
three
reactive,
apis
they're,
not
part
of
the
core,
the
core
selection
of
apis,
and
I'm
still
trying
to
find
out.
Why
and
there's
also
micro
profile
graphql,
that's
actually
newer
than
the
others
there.
So
so
there
is
support
for
reacted.
Java
going
on.
B
I
know,
there's
rx
java,
and
you
know
some
of
the
other
things
out
there
so
but
yeah
so
there
is,
there
is
you
know,
reactive
java
is,
is
you
know,
definitely
popular
and
then
the
late
majority?
Of
course
no
surprise
by
any
of
these.
I'm
not
gonna,
go
through
them,
one
by
one.
You
know
so,
of
course,
job
aiden
and
everything
else
hibernate.
B
B
What
I
wanted
to
mention
before
about
kotlin
was
you
know.
Kotlin
was
just
another
jvm
language
until
android
made
it
the
official
language
of
android
development
and
that's
when
that
really
exploded,
and
that
happened
about
three
years
ago.
I
remember
jay,
ruby,
not
quite
sure
who's
using
jruby.
I
haven't
really
paid
attention,
so
you
know,
but
it's
in
the
early
majority
there
and
then
the
open
jdk
and
the
different
non-oracle
bills.
You
know:
there's
been
amazon,
coretto
adopt
open,
adopt
open,
jdk
azul.
A
B
I
say
oh
cool,
welcome
to
everybody
all
right,
so
here's
growl
vm
and
this
that
first
bullet
there
is
a
quote
from
the
website.
At
least
it
was
at
one
point,
so
a
universal
virtual
machine,
for
you
know
converting
native
code
into
I'm
sorry
code
in
like
javascript
python,
anything
that
is
interpreted
into
into
native
code.
So
you
see
you
know,
ruby
python.
I've
been
trying
to
play
with
python
a
little
bit
on
that
one.
It's
called
jeep
gorilla
python.
B
B
You
know
wake
them
up
for
the
year
3000,
but
but
yeah
it's,
I
guess
cobalt
has
enough.
Has
enough
out
there
to
support
that
so
grav
vm
has
a
utility
known
as
native
image
and
what's
what's
kind
of
interesting
is
the
earlier
versions
of
gravim
the
native
image
was
included
and
then
ever
since
19.0
came
out,
they
they
decided
to
say,
let's
you
know,
let's
use
the
the
growl
utility
gu
as
it's
called
and
you
know
have
to
install
it
separately.
B
A
B
Attempt
to
clear
scroll
back
history,
that's
okay!
That's
fine!
I've!
Never
seen
that
before
with
with
my
terminal
all
right,
so
I
I'm
a
big
fan
of
craft
beer.
So
of
course
some
of
my
presentations
I'll
have
to
do
something
craft
beer
related.
So
I
happen
to
have
this
and
I
believe
this
is
on
github.
So
you
can
try
to
find
this
all
right.
So
we'll
we'll
do
a
nbn,
clean.
B
B
B
A
B
Yep
all
right,
so
I
have
a
beers,
a
beers,
endpoint,
okay
and
then,
if
you
want
to
know
more
about
it,
I
should
have
done
it
by
the
id
number.
But
you
can
do
it
like
your
pumpkin
imperial
ale
and
then
it
gives
you
all
the
relevant
information,
the
beer
type.
What
the
abv
is.
You
know
who
the
brewer
is
so
there's
a
you
know.
There's
a
brewer
in
the
jason
here
and
I
noticed
l
is
in
lowercase
gotta
fix
that,
but
we
also
have
brewers
as
an
endpoint.
B
So
and
then
you
have
everything
right
there.
So
that's
not
the
point
of
this.
I
just
wanted
to
show
that
off
myself
and
I
could
have
sworn
I
saw.
It
start
the
here
we
go
startup
completed
in
just
over
three
seconds,
all
right,
so
we'll
kill
that
okay
and
then
so.
We'll
do
here
native
image.
Now
there's
a
couple
of
ways
you
can
do
this,
you
can
run
the
actual
native
image
itself
and
if
you,
when
you
find
it.
B
Right
and
it's
in
my
graw
vm
java,
11,
okay,
so
that's
what
you
can
find
you
can
also
in
maven
you
can
have
a
dependency
or
an
executable
four
for
that
itself.
There's
a
couple
different
ways:
you
can
do
this,
but
in
this
case
a
native
all
image
and
yeah
advanced
jar
and
then
targets
and
then
and
then
the
jar
file
itself.
B
B
This
will
actually
take
a
little
bit
and
when
you
know
it's
working
right
when
you
see
all
these
different
outputs
here
on
what
it's
doing
so
it's
compiling
everything
you
know
from
byte
code
to
to
native
code
and
a
good
friend
of
mine,
tom
who's
been
retired
now
about
seven
years
or
always
say
so
so
who's
from
out
of
town-
and
I
think
the
answer
to
that
is
a
lot
of
a
lot
of
you.
So
where
is
so?
Where
are
we
seeing
people
from
from
out
of
town
if
you're
looking.
B
I
know
we're
worldwide
yeah
india,
that's
great,
so
this
is
at
this
point
too,
brazil
and
south
of
brazil
awesome.
So
so
here's
I
got
this
I'm
on
the
program
committee
for
the
jakarta
one
conference,
that's
on
december,
8th.
So
if
you
haven't
done
so
already
and
if
you're
interested
in
participating,
it's
free,
of
course
so
and
it
goes
from
six
a.m,
to
six
p.m.
It's
it's
a
lot
less!
B
B
You
know
that
that
have
happened
so
far.
So
there's
the
regular,
jakarta
one
and
then
there's
been
a
jakarta
one:
brazil,
a
jakarta
one,
japan,
I
believe,
and
a
couple
of
others
here
so,
but
it's
really
cool
I
was.
I
was
asked
to
be
on
the
programming
committee
to
this
year,
so
I
was
honored
to
have
been
part
of
that.
So
so
that's
on
december
8th
and
you
know
hopefully
hope
to
see
you
there,
so
this
is
taking
a
little
longer.
A
So
the
trade-off
that
you
get
there
or
the
reason
why
you
make
a
decision
to
adopt
or
not
to
adopt
is
typically
based
on.
If
you
need
fast,
startup
performance
like
a
serverless
function
or
peak
performance
of
something
that's
long
running,
and
what
I'm
hearing
from
a
lot
of
people
is
that
growl
vm
tends
to
win
on
that
startup
performance.
B
Yes,
that's
right,
yeah,
thanks
for
the
permission
yeah.
I
forgot
all
about
that
yeah.
That
was
a
trade-off
right
for
that,
but
yeah.
This
does
take
quite
a
bit
of
time
here.
So
so
so
hello,
don
and
and
michael
micro
naught.
Both
support,
brawl,
vm
quarkus,
I
think,
is,
has
raw
vm.
You
know
in
it
as
well.
A
Yeah
quercus
has
growl
vm
baked
into
it,
which
is
really
cool
and
one
of
the
things
I'm
a
big
quercus
proponent.
I
think
that
group
has
done
an
excellent
job
from
the
people
that
I've
seen
talking
about
it.
There's
always
something
impressive
there.
When
I've
looked
at
quercus
and
actually
used
it,
some
of
the
things
that
are
good
is
you
can
run
it
in
native
hotspot
mode.
A
It
just
makes
it
very
easy
to
run
on
your
local
machine
with
full
java
debugging,
all
that
native
experience
and
then
automatically
port,
that
application
up
to
the
cloud
for
low
operational
cost
is
just
an
excellent
thing
that
the
framework
offers
some
of
the
times.
I
know
because
it's
owned
by
red
hat
and
they
have
mandrel
it's
likely.
They
will
go
that
route,
but
to
date
I
think
it's
predominantly
based
on
growl
vm.
B
Oh
yes,
yes,
it
seems,
like
it
almost
seems
to
me
like
spring-
has
sort
of
been
in
the
sort
of
the
background.
Lately.
You
know
with
all
these
newer
frameworks
having
come
out
so
but
yeah
they're
still,
of
course
alive
and
well.
There
was
a
technical
article
written
by
sergio
felix
back
in
march,
I
believe
on
spring
route
and
deploying
to
google
cloud.
I
I
happen
to
review
that
and
will
be
part
of
a
microservices
series
coming
out.
Hopefully,
within
the
next
month,
I'd
say:
that's
something.
A
A
Of
in
terms
of
which
applications
you
see
you're
the
the
early
adopters
early
majority
late
majority,
I
see
a
huge
amount
of
spring
boot
like
I
just
I
run
into
it
on
a
regular
basis
and
encounter
it
all
the
time.
It's
a
perfectly
fine
framework
to
use,
there's
nothing
wrong
with
being
in
the
late
majority,
the
early
majority.
B
Oh
kind
of
kind
of
copied
well
copied
a
little
bit
of
you,
know:
they're
they're,
starting
the
server
itself
spring
boot.
It's
you
know
in
maine,
it's
springboot.run,
or
is
it
boot.run?
Something
like
that?
It's
been
a
while,
let's
finish
finally,
and
then
micro
naught,
it's
micro
naught
that
one
all
right.
So
so
this
finished
so
sorry
about
the
weight
on
that.
But
I
think
we
had
some
good
discussion
on
that.
B
B
B
All
right,
yes,
we
allow
that
incoming
connections
and
here
you'll
see
that
the
starter,
the
server
started
up
in
66
milliseconds.
So
that's
you
know
quite
the
quite
the
factor
right
there,
okay,
so
so
that
that's
the
difference
in
there,
but
the
executable
that
tends
to
be.
You
know,
kind
of
big
which
sorry
they
need
to
do.
That.
A
B
B
That's
true,
absolutely
all
right.
So,
let's
resume,
let's
hear
presents
okay,
all
right,
so
corkus
is
what
you
know.
This
is
from
the
website
itself
for
coupon
eaters,
kubernetes
native
java
stack
tailored
for
open,
gdk
hotspot
and
crawl
vm,
okay,
crafted
from
the
best
of
be
java,
libraries
and
standards,
okay,
so
and
they
they
on
the
website
too.
B
It
says
supersonic,
subatomic
java,
it's
cohesive
fun
to
use
full
stack
framework,
and
what
I
learned
recently
is
cork
is
is
actually
a
portmundo,
which
is
a
word
I
learned
from
victor
grazie
by
the
way.
So
that's
I
always
like
to
use
that
when
you
have
concatenate
two
words
together
or
you
know,
make
up
a
new
word
based
on
two
words.
So
it's
made
up
of
quark,
which
of
course
is
a
is
a
particle
element.
B
Okay
and
then,
of
course,
us
meaning
all
of
us
in
the
java
community,
the
latest
version
is
1.92,
and
what
I
like
about
this
is
that
there
is
a
a
starter
page.
That's
another
trend,
I
I
don't
think
we've
we've
really
have
mentioned,
and
it's
it's
the
the
emergence
of
all
these
starter
pages.
It
started
with
spring,
I
think
it's
a
spring
initializer,
they
call
it
and
then
micro
profile
has
one
corcus
has
one
and
I'm
sure,
there's
others,
I'm
not
forgetting
at
the
moment.
B
So
but
yeah,
it's
really
it's!
You
can
really
get
going
quickly
and
we'll
show
you
an
example
of
that
in
a
minute.
So
this
is
just
a
small
tip
of
the
iceberg
list
of
the
best
of
breed
libraries
that
are
supported
in
here
does
you
know,
have
the
the
small
rye
implementation
of
micro
profile
and
I
believe
small
right
is
red
hat
I'm
not
mistaken.
They
could
be
wrong
on
that,
but
you'll
see
verdicts
in
there.
Jax
rs
and
you
know
all
the
others
and
cdi
et
cetera.
B
Either
brother
either
everybody's
groaning
or
or
happy
about
this
at
some
point,
so
it
start
right
here,
so
this
is
code.quarkus.io
right
and
then
it
has
default
group
names.
You
can
change
that
if
you
want
but
we'll
just
stick
with
this,
but
you
can
choose
all
your
extensions
and
you
know
I
mentioned
those
few
items
right
in
here
but
check
it
check
all
this
out
right.
It's
got
a
lot
of
apis
that
you
can
incorporate
into
your
app
all
right.
B
So
here's
you
know
the
small
jwt
open
api
oops.
I
didn't
want
that
there,
let's
close,
that,
thank
you
see,
hibernates
you
know
and
so
on
and
so
on,
and
I
don't
know
what
I
picked
earlier
so
yeah
the
list
goes
on
and
on
and
let's
say:
let's
do
a
quick
health
fault.
Tolerance,
okay,
need
to
report
a
micro
profile,
all
right
and
so,
like
I
said
you
could
do
what
you
want.
You
can
generate
your
application,
download
it
as
a
zip.
B
Okay,
okay,
now
what
I
like
about
the
quarkx
is
that
when
you
run
this
as
nbm
package,
I
believe
cork
is
dev
poland,
it's
always
good
to
read.
You
know
to
to
practice
these
things
before
presentation,
because
I
did
corpus
dash
dev
earlier
this
morning,
forgotten
forgetting
that
it
was
a
colon
there.
Of
course,
I
got
an
error
message,
but
anyway,
so
what
it
does
it'll
it'll
start
the
application.
A
Yeah,
so
if
I
can
chime
in
one
of
the
nice
things
that
I've
seen
people
talk
about
quercus
and
one
of
the
reasons
I
like
it
is
this
quarkus
colon
dev
gives
you
the
full
rapid,
reloading
automatic
hot
reload.
So
if
you
have
your
integrated
development
environment,
open
as
you
change
code,
it
automatically
reloads
and
they're
actually
quercus
started,
it
looks
like
oh
did
you
stop
it.
B
B
B
B
Okay,
now
it's
supposed
to
do
that.
This
was
if
this
wasn't
a
cli.
I
think
it
would
automatically
rerun.
But
if
we
hit
enter
to
restart
you'll,
see
that
it'll
say
hello
commander
there,
so
it
does.
You
know
I
want
to
call
it
a
hot
response
or
not,
but
as
eric
mentioned
before
it
does
have
that
hot
reload
that
you
don't
have
to
do
a
full,
recompile
and
store
it
again.
So
that's
a
nice
feature
of
that.
So
you
can.
You
know
you
can
do
a
lot
of
a
lot
of
things
with
that.
B
A
Oh,
there
is
a
question.
Sorry
I
didn't
realize
these
questions
were
in
a
different
area.
I
was
trying
a
micronaut
app
where
I
have
mysql
as
a
database
and
was
using
jpa
for
crud.
I
defined
my
entity
class
with
lombok.
For
some
reason
it
is
not
recognizing
lombok
ending
with
a
compilation.
Failure,
oh
boy.
B
B
A
Put
it
on
for
for
context,
because
we're
talking
about
quark
is
here.
One
of
the
things
that
it
has
that's
particularly
interesting
is
for
hibernate
and
jpa.
It
has
an
entity
framework
called
panache
where
you
just
code,
a
basic
plain
old
java
object,
but
you
extend
a
panache
entity
and
from
that
you
have
all
your
get
set
storage
integrated
directly
with
hibernate,
which
makes
it
extremely
easy
to
code.
You
don't
have
to
worry
about
any
of
the
database
materials,
even
though
you're
certainly
welcome
to
pay
attention
to
it.
A
If
you
like,
so
it
just,
it
again
makes
that
easy,
also
by
making
kind
of
the
default
choices
of
what
you'd
get
or
the
way
that
you
would
integrate
it,
especially
with
a
crud
app
and
one
of
the
things
that
panache
did
particularly
nice.
Is
they
don't
actually
expose
the
sql
query
or
they
make
it
hard
to
get
access
to
the
sql
query
which,
for
me,
from
a
security
perspective,
because
I
deal
with
applications
that
get
broken
into
a
lot?
A
B
B
We've
noticed
a
sharp
decline
in
the
use
of
oracle's,
java,
binaries
and,
and
part
of
this,
I
think,
is
because
oracle
doesn't
provide
support
for
zero
cost
java
binaries
for
more
than
six
months
after
release,
and
these
are
the
non-lts
versions
on
there
and,
as
I
mentioned
before,
organizations
are
sticking
with
java,
8
and
java
11.
You
know
java,
11
being
you
know,
20
and
java.
8
being
being
more,
I
mean
some
organizations
are
doing
a
little
bit
of
this
and
there's
a
pie
chart
in
the
next
page.
B
So
so
that's
that's
something
that
we've
seen
over
here.
So
I
don't
know
if
oracle
is
going
to.
You
know,
review
their
six-month
upgrade
and
maybe
make
a
change
moving
forward,
but
that's
up
to
them
to
you
know
to
do
and
we'll
see
about
that-
and
I
mentioned
before
of
you
know:
the
market
is
turning
to
non-oracle
providers
of
java
binaries
and
adopt
open
jdk,
which
has
been
brought
into
the
eclipse
foundation
now,
and
they
called
it
a
they
call.
B
It
adoptium,
which
I
know
a
few
people,
have
actually
ridiculed
the
name
it's,
but
it
does
sound
kind
of
you
know
kind
of
funny,
but
that
you
know
that's
what
it
is
but
and
also
azul,
zulu
and
and
also
amazon
coretto
have
been
out
there.
Coretto
has
supports
both
eight
and
eleven
and,
interestingly,
I
believe,
they're
not
supporting
any
of
the
other
non-lts
versions.
Now
it's
it's.
You
know.
B
B
B
Yes,
thank
you
yeah
this
ben
evans
company
that
put
this
out
earlier
this
year
and
you
know
the
other
slices.
You
know
obviously
there's
they're
very,
very
small
relative
to
that.
So
that
speaks
to
that
and
then
also
too
the
providers.
You
know
the
percentage
of
those
that
are
being
used,
and
you
know
it's
about
75
percent,
or
so
you
know
oracle,
and
then
you
can
see
the
smaller
percentages
now
iced
tea,
I'll
I'll,
be
completely
honest.
B
B
It
was
created
as
a
response
to
to
oracle's
dragging
their
feet,
and
you
know
for
lack
of
a
better
way
of
saying
it
on
in
getting
java
ee
out
it's
it
was
supposed
to
have
come
out.
I
guess
in
2015
you
know,
but
they
they
kept.
They
kept
delaying
it
for
for
whatever
reason,
so
they
a
group
of
vendors,
then
that
would
be
my
for
micro
profile-
would
be
tommy
tribe,
ibm
red
hat.
And
what
am
I
missing?
B
Ibm
red
hat
tommy,
oh
payara,
they
got
together
and
came
up
with
this.
You
know
with
microprofile
initiative
the
the
initial
three
apis,
which
are
considered
the
minimal
for
a
micro
services
based
application
are
context
and
dependency
injections,
see
you
know
otherwise
known
as
cdi
jax,
rs
and
jason
p,
so
for
processing,
jason
files.
So.
B
B
Okay
just
want
to
get
my
notes
here.
There
are
12
apis
on
there
and
those
are
part
of
the
core
of
micro
profile
and
which
I'll
show
in
a
minute
here.
Microprofile
4
is
on
the
verge
of
being
released.
It
was
supposed
to
have
been
released
in
in
june
of
this
year,
but
eclipse
had
asked
the
initiative
to
put
together
a
working
group,
and
that
was
the
delay,
so
they
have
a
working
group
now
and
and
they're
working
with
the
jakarta
ee
working
group
as
well.
B
B
B
You
know
for
building
more
robust
microservices
applications.
Now
these
are
for
3.3.
So
you
know,
config
is
going
to
be
bumped
up
to
two
full
tolerance
to
3.0
health
3.0.
You
know
so
on
and
so
on.
So
and
another
interesting
thing
is
open
tracing
it's
it's
at
some
point.
The
open,
tracing
and
open
consensus
have
merged
to
create
open
telemetry,
and
there
was
some
discussion
about
dropping
open
tracing
in
favor
of
open
telemetry,
but
that's
been
delayed
from
that.
So
look
for
more
on
that,
as
micro
profile
emerges.
B
Okay,
so
live
demo,
we'll
do
a
quick
one
here.
We
have
time
for
this.
Hudson
11,
52,
yeah,
you're,
good!
Okay!
Great!
Thank
you
all
right.
So
this
is
start.microprofile.io.
Okay,
very
similar
here,
not
as
not
as
busy
I'd
say
right
so
again
it
has
default.
Artifact,
ids
group
ids
and
you
can
choose
your
version.
Let's
choose
the
latest
choose
3.3!
B
Okay,
I
don't
know
why.
Sometimes
it
allows
you
to
choose
your
jdk
version,
but
it's
not
doing
it
or
maybe
maybe
this
one.
Let's,
let's
do
open
liberty.
There
we
go
and
let's
do
java
11..
Let's
just
choose
a
couple
health
check:
let's
do
metrics
okay,
and
we
can
do
let's
do
tolerance,
okay
and
we'll
download
it
and
that's
a
demo.zip
by
default.
Okay,
so
that
we
got
some
keep
that.
B
B
So
tokyo,
here's
where
you
know
you
have
your
demo
right
here
in
your
source
code,
all
right!
So
all
you
do
here
since
we
chose
open
liberty
as
the
runtime
okay,
we
can
do
mvm
package
and
then
liberty
run
what
you
can
do
you
can,
you
know,
create
a
war
file
and
you
can
deploy
it
to
you
know
the
open
liberty
server,
I
mean
that's.
You
know,
there's
more
way
to
do
a
lot
of
this
stuff.
This
is
just
quicker
to
do
that.
B
B
You
know
I
I
really
like
how
microprofile
has
evolved
over
the
past.
You
know
four
years
and
you
know
more
recently.
They
they
do
offer
the
java
community
to
participate
in
their
weekly,
what
they
call
hangouts
it's
on
tuesdays
at
2
pm
eastern
time
this
morning.
I
know
it
could
be
running
but
but
yeah
and
it's
a
zoom
call
and
it's
you
know
they
welcome
everybody,
and
so
I've
been
participating
here.
You
know
you
know
here
and
there
and
all
that,
so
you
know
I've
gotten
to
know
the
folks.
B
B
There
we
go
all
right.
So
what's
nice
about
this,
it
has
a
built,
a
built-in
index,
html
file,
to
give
you
all
the
different
endpoints,
which
I
think
is
nice
as
opposed
to
okay,
which
one
is
it
you
can
you
can
do
all
these,
of
course
right?
But
I
think
this
is
a
nice.
You
know
start
page
for
that,
so
you
can
do
you
know
jack's
endpoint
to
say
hello
world.
You
know
so
on
and
config
fault
tolerance,
health,
okay,
so
this
is
a
default
health.
B
B
A
B
Maybe
it's
metric,
I
don't
know,
but
it's
why
it's
not
working,
but
you
know,
but
again
you
can
also
come
up
with
your
custom
metrics
as
well.
There
are
things
you
can
do
like.
I
contributed
to
apache
a
a
histogram
kind
of
based
it
on
the
last
15
days
of
the
data
of
temperatures
in
new
york
city,
for
example.
You
know
something
like
that.
So.
A
B
You
have
a
lot
of
flexibility
to
do
your
own
thing
and
custom
for
the
application
that
you're
building.
So
I
think
that's
really
nice
there's
so
much.
You
can
do
with
that
and
there's
a
number
of
implementations,
there's
small
rye
and,
of
course
you
know
open
liberty,
payara,
you
know
all
the
usual
suspects
are
doing
that.
So
with
that
I
know
we're
getting
near
the
end
here.
B
Okay,
okay,
I
have
a
bunch
of
resources
here.
You
know
by
some
of
us
that
have
that
are
that
are
relative
to
this
presentation.
The
trends
report
from
last
year
glowing
is,
I
know
something
that
has
been
relatively
new.
The
reason
I
put
that
in
there
in
the
in
the
report
itself,
there
are
some
quotes
by
some
folks
in
the
java
community,
some
of
the
java
luminaries.
You
know
talking
about
different
things
about
java,
11
or
growl
vm,
etc.
You
can
you
can
look
at
that.
B
Yeah
we'll
have
to
write
about
it,
some
more
actually,
you
know
maybe
but
yeah
there's
a
number
of
things.
I
know
you
know
I
mean
all
of
us.
Have
our
you
know
interests
and-
and
you
know
I
tend
to
you-
know-
focus
a
little
bit
more
on
jakarta,
ee
and
michael
profile,
and
you
know
everything
going
on
so
yeah.
I
think
we,
I
think
all
of
us
editors
cover
a
lot
of
good
things,
but
yeah
there
are
some
things
that
need
to
be.
You
know,
have
more
focus
as
well
yeah.
B
You
can
read
all
about
how
micro
profile
you
know
at
the
road
to
micro
profile.
Four,
that
I
was
just
mentioning
some
more
details
about
that
and
let's
see-
and
I
can't
indulge
in
one
of
these
now
because
it's
a
noon
time
here
and
I'm
at
work
I'd
be
fired.
But
if
you
happen
to
be
you
know
in
a
time
zone
where
it's
after
after
work,
then
please
you
know
enjoy
and
as
we
say
in
germany
and
first
of
all,
thank
you,
for
you
know
spending
an
hour
with
us
today.
B
B
I
know
he
had
some
things
to
do
so.
Yeah,
I'm
sorry
I
was
on
enough,
but
you
know
nothing,
nothing
more,
to
add
thanks,
awesome
so,
but
yeah.
So
I
don't
know
how
many
people
are
aware
of
info
queue
or
region
for
q
on
a
regular
basis,
but
but
please
reach
out
to
us.
You
know
our
bios.
I
actually
not
a
first
page,
our
bios
there's

bios.
I
think
it
has
our
email
address
on
there.
