OK, I did a 'cvs update' right now and rebuilt my clean cvs checkout
from 08:30 today.

Admittedly, the PR23557 testcase starts instead of crashing the VM,
but I wouldn't call it fixed... (SuSE Linux x86, jamvm 1.3.2, ctwm 
WindowManager):

With Graphics2D enabled, the main window appears, but I get the
Graphics2D.copyArea UnsupportedOperationException as soon as I try
to open the JComboBox drop-down list:

/opt/jamvm/bin/jamvm -mx200m -Dgnu.java.awt.peer.gtk.Graphics=Graphics2D PR23557
Exception during event dispatch:
java.lang.UnsupportedOperationException
   at gnu.java.awt.peer.gtk.GdkGraphics2D.copyArea (GdkGraphics2D.java:1397)

   ...
   
   
Without Graphics2D, I can open the drop-down list, but the drop-down-
list-window is way to big, and gets BIGGER each time I open it anew. 
This is pretty funny to watch, but not really useable. Also, clicking
somewhere outside the actual text-labels in the big drop-down window
crashes:
