State of Java on OE

State of Java on OE

[Steven Osborn]

Is anyone using Java on OE devices right now?

meta-java - no release branches.  Seems to only be focused on master.
I've had trouble even finding a revision that will compile on Morty.

meta-oracle-java has a Morty branch, but the URI for the binaries is
bad so it fails to install.

Overall it seems like Java is not a very favored or platform at the moment.

koen@beast:/build/v2016.12$ cat .repo/manifests/default.xml  | grep java
  <project name="meta-java" path="layers/meta-java" remote="yocto"
revision="a265b31ec7d022be254abdf959360a7624208585" upstream="master"/>

That generates an openjdk-8 good enough to run jenkins on x86-64, no idea
about other archs.

Yep. Me.

I'm using the current master branch with YP jethro for running OpenJRE 7 
in mixed mode on ARM systems. And I'm currently migrating my platforms 
to master (->pyro).

So it works fine for me. Only problem is that we cannot upgrade OpenJDK 
to the current patch level for ARM because JIT was broken:

Haven't tried meta-oracle-java in the last couple of years (due to 
license issues).

That's maybe true. But help in the meta-java layer for fixing problems 
is (if you have some spare time) always appreciated ;-)

We are using oracle for several years now. And yes, we pay for it.
This URI is not bad, you need an account for some of the binaries.

I forgot to mention a annoying and stupid bug: if host and target match it
will use host g++ to compile, which breaks in my case because that's gcc 4.9
which doesn't understand the dse flags the recipe is passing in.

I have got the same problems - the missing of release branches in
meta-java is quite confusing. -master does not work with last releases,
and everybody have to find working commit id for each release. And after
that, cherry-picking something from -master to fix global issue (it was
for me dependency's issue with classpath).

Maybe we have to try to propose the maintainers to set release branches
as usual.

Stefano

You can add an empty class to make 'master' work with 'morty':

https://github.com/Angstrom-distribution/meta-angstrom/commit/2eca0f1c932f098eb7fd877c5b00225408b2e42d

And I had to do this to make it build:

https://github.com/Angstrom-distribution/meta-angstrom/blob/709abee819ee349dab873f6abb02c404b2c65331/recipes-tweaks/ecj/ecj-initial-native.bbappend

With this I can build 'openjre-8' on debian and fedora hosts for armv7 and
x86_64. It even runs jenkins, but it used 4x the amount of memory openjdk-7
did :(

Koen

fyi: I'm currently working on fixing openjdk-7 to work again with
current master. I think I'll be able to post the patches today, or at
least this week.

So it looks like there is a morty branch now, but it includes a commit that 
only works with master due to inheriting relative_symlinks (as also noted by 
Koen). 

Maxin (or someone else with push access), could you please fix the morty 
branch?

Thanks,
Paul

Hi Paul,

Updated the morty branch today. Sorry for this mess-up.
