Mac Black Screen Java Error

[Denbox]

I am trying to get FTB to work on my mac computer. I have tried different packs, but I get the same log and error. It seems to be related to java but I don't know what to do. Here is the log. http://pastebin.com/R8Mbqfjk

I haven't installed any mods and the error is a black screen after the FTB logo and after the little window saying that it is setting up my game environment.
Thanks in advance.

That's an unknown paste ID, you'll need to resubmit it.
Also, chances are you're using Java 7, when you should be using Java 6.
