Mac Yogcraft Crashing on Start-up

[Mastachief54117]

So I've been playing Yogcraft for a couple of weeks now, and it's pretty much worked fine up until now. But today I open up the launcher and try to play, as normal, and it crashes. I re-try. Four times. Nothing works... I've done some searching online as well as looking through the files to make sure everything seems about right, and I think it may be due to the fact that Java updated yesterday in a routine software update, but I'm not sure.
Here is the crash-log:

Any help would be greatly appreciated. Thanks.

I seemed to have fixed it after re-installing then adding and removing random stuff 'til it worked. I think the problem was based around an issue with Flan's mod.
