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 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)

Why so?
Sorry if it insulted you somehow. I'm myself using java on arm32 board. And it is really painful. However I'm java developer, so it is only ... nature... what incline me to it. Because of speed of java on arm32 I sincerely believe that all except java developers really dont have java on arm32.

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.
