Eclipse Mod Help

Hey guys I'm making a mod with forge and when I try to run it thru eclipse it instantly crashes and gives this message:

_NSJVMLoadLibrary: NSAddLibrary failed for /libjawt.dylib
JavaVM FATAL: lookup of function JAWT_GetAWT failed. Exit

What does it mean and how can I fix it?

Please help and you will gain a subscriber!
