Seems to be another JVM implementation spec related crash. This only happens when using OpenJDK to launch.

This issue was on ftb interactions, so I suppose I'll have to poke them for a forge update, haha.

This was supposibly resolved in a forge update, unfortunately there's nothing I can really do about it from my end.

You do apppear to be running an older forge, so update that if possible.

what version do you recommend @Shadows-of-Fire we're already running slightly ahead of forge recommended build, beta forge builds worry me on production packs :-/
