I'm doing tests for the machine/distro combinations stated in the README
before pushing to master. Therefore it should have worked back then.

Nonetheless I'm currently working on updating openjdk-8 to the latest ga

make sure nothing broke over time.

So maybe I could get something out of this.

Nothing that comes to my mind directly, but I'll take a look into this.

So your "custom machine" is also x86-64?
