Yes, we previously had a commercial version, and now someone (not me)
thought if we could switch to openJDK.
We have already switched with openJDK for our x86 platform.

So it seems that jdk8u162 with "zero" jvm-variant is my best bet right now.
Even though it is not java compliant and not really production quality.

I don't have the logs right now. I was cross-compiling this in December and
I got to where I said: only managed to compile "hotspot" target and "jdk"
target crashed.
And then we had to change the cross-compiling tool chain and build setup.
Now I am cross-compiling using yocto and still have trouble running the
config script to generate the makefiles for openJDK. And wanted to know in
advance if I was on a good path or there was a better alternative.

I can try to re-make the old cross-compiling tool chain and show you the
errors that I have. But I remember the linker was saying it can't find
the *definition
for printf()* when compiling "jdk" target, even though "hotspot" target
worked, and I saw printf() in that code as well.

I will continue with the "debuging" of the config script and post when I
get any errors.


Thank you very much for the help,
Radu
