Yeah. You could try to merge EventQueue.invokeLater from GNU Classpath
in, or the whole class.

The Kaffe-awt (what you are using) is an peerless AWT implementation
which doesn't inlcude Swing, it only supports swing using Sun's non-free
Swing111.jar. As you have seen, it would need to be a bit updated to
work with Classpath's swing. Such patches would be most welcome!
The classpath AWT implementation uses peers, so a good deal of the
internal design is a bit different. Ideally, someone should write a
wrapper around the peerless AWT backends in Kaffe that would make them
useable from within Classpath, or port them to the peer-based
architecture of GNU Classpath. I've CC:ed James and Stephane, who tried
to do that for the Xlib and Qt peers.
