I'm attempting to run MegaMek on cacao + classpath-0_93-branch. I see many

and (likely as a result of these exceptions) GTK widgets aren't being painted
correctly.
I'm investigating...
Found that already. Lifting this patch from head to the release branch
now:
2006-12-03 Mark Wielaard <mark@xxxxxxxxx>
* gnu/java/awt/peer/gtk/GtkComponentPeer.java (paintArea): Renamed
to currentPaintArea.
(paintComponent): Work with local reference to currentPaintArea.
(updateComponent): Likewise.
(coalescePaintEvent): Set currentPaintArea.
Plus some of the others we found during testing this weekend.
Please retest in half an hour when I flushed all appropriate patches to
the branch.
OK, that fixed the exception, thanks. I'm still seeing the GTK widget painting
problems, and also this when I try to show MegaMek's documentation widget:
