Hello good people of Fedora!

Most of you is probably facing very slow java (java-1.8.0-openjdk) on
any arm32 device.
The luckier from you already tuned arm32 boards to not need java at
all.

But behold! The "new"[0] OpenJDK for arm32 crossed milestone when it
can be widely used.

If you need java on your arm32 board, try to replace (or install
alongside) your java-1.8.0-openjdk
special package java-1.8.0-openjdk-aarch32
The theoretical speedup[1] is aprox 100x faster. Practical speedup is

100x speedup, and u think that there will be someone who use java on

I do :)
arm? If serriously, i will try. ty

If nothing else does, koji builders are. And java stack is build for arms.

If no other benefit then 1/10 waiting for arm32 koji builds, then it fulfilled its purpose.

But I believe the package will have also human-target audience.

hth!

somewhere between 10x-50x (for
now). You can see it in koji:
http://koji.fedoraproject.org/koji/buildinfo?buildID=780150 - java
build by "normal" java on aarch32
- 13 hours
http://koji.fedoraproject.org/koji/buildinfo?buildID=802986  - java
build by "new" java on aarch32 -
2 hours

We have already slowly started to enable virtual java provides:
f24 - no
f25 - java
f26 - java+java-devel

Please *don't* change your specfiles (if any) to something like:

ifarch arm32
   BuildRequires java-1.8.0-openjdk-aarch32-devel
else
   BuildRequires java-1.8.0-openjdk-devel
fi

You will mess up things a lot. The provides will come with stability
and  in longer run the package
will be merged back to java-1.8.0-openjdk packages (as it is still
the same friendly openjdk, just
with different virtual machine)
