I don't have any information on that. What I did dig up since then is  
that there is a bug in the -XstartOnFirstThread mode, which is needed  
for Mac SWT:

http://lists.apple.com/archives/java-dev//2008/Feb/msg00179.html

I added this fix to the beginning of Rune#main and it stopped exiting  
silently -- instead it gets to the point of having a menu bar, but  
hangs instead of responding to events.


I tried downloading newer SWT versions (3.3.2 and 3.4), but the  
behavior did not change.

(By the way, the swt.jar is architecture-independent, so we shouldn't  
have two copies in mac/ppc/ and mac/x86/. If I upgrade it I'll put it  
in bin/mac/ and symlink from the arch directories -- or should I  
revert the change (which I didn't write) that looked for swt in arch- 
specific dirs?)
