There's a problem with Mac + SWT, try taking jme-swt and swt-fake off your classpath.
Out of curiosity what are the ramifications of not having the library?
No SWT support (SWT GUI + jME Canvas in the same window. Eclipse recently released a proper library for cocoa.. I've been testing it with pretty good results, might stick it in the repository in the next few weeks..
Thank you for your help, it's really appreciated.
Now do the greater deed and be the next person to pass on some knowledge ;)
