Thanks for the input Andrew, good to know it makes the powerpc build
non Java compatible (I assume this means JCK, right? I never ran it
for non-intel systems)

That particular patch has been added to Debian's OpenJDK 7 back in
2013, which was then carried over to OpenJDK 8 as well. It was based
on this bug report:

If anyone has a better fix, I would be glad to replace the patch - or
remove it altogether if it makes upstream to OpenJDK 7 and 8. ;-)
