Mac Modpacks will not launch properly: gets to FML setup, black-screens, then closes the MC window.

The title explains what happens very well. http://pastebin.com/89E5yg8v has the log from the FTB console.
I think that lines 101-102 cause the launch fail.

You should be using Java 6. In my troubleshooting guide (link in signature) there should be a link to the apple support site for help on how to revert to Java 6.
