Have you tried resyncing with the latest Classpath sources already?
AFAIK, the latest merge is quite some time ago and I remember to have
fixed a couple of repaint related issues in Classpath's AWT code. I
tried the example of your previous email regarding AWT (the same as the
attached program?) against Classpath and that seemed to work.

I will look into your issues tomorrow when I'm back at work.
Promised :-) I was so very busy the last couple of days/weeks...
