Re: -Djava.awt.headless=true and Gtk...

Hi Martin,

SableVM uses GNU Classpath for its class libraries.  I am not a specialist
of GNU Classpath and its AWT code.  Maybe someone else on this list knows
more about this code, but you might want to also ask for help on the GNU
Classpath mailing list:

  http://lists.gnu.org/mailman/listinfo/classpath

The developers of the AWT code are subscribed to that list.

Hoping this helps.  :-)
