Mac Problems With Loading Launcher (Beta)

[Craftme2theMax]

I tried giving the launcher to my friend who has a Mac and this happened: http://pastebin.com/jJNvRgMy I gave him the FTB_Launcher-0.1.2-Beta.jar file.

it appears to be this line:

net.ftb.gui.LauncherConsole$OutputOverride.write:68 From Console: java.lang.NoClassDefFoundError: javax/swing/Painter

A simple java update should fix this problem. If not, then I am not sure how to fix it.
