Exception in thread "AWT-EventQueue-0" java.awt.HeadlessException

[David Orriss Jr]

I ran into the same problem here.  So I included the
-Djava.awt.headless=false command line option.  I got a more descriptive
error.  Not sure why tho.. X11 is running and I've set the correct value for
DISPLAY, as far as I know.

Exception in thread "main" java.lang.InternalError: Can't connect to X11
window server using ':0.0' as the value of the DISPLAY variable.
