Forgot to add that you need to
- rm lib/classes.tar

Jamvm comes with precompiled classes and won't recompile your changed
sources except when you explicitly remove the classes.tar file first.

Since I did actually forget the rm lib/classes.tar before creating these
results the old version had FAILs for the new regex tests. I uploaded a
new version of the results file (13202 PASSes and 226 FAILs).

I should have mentioned that there is a Test.java and TestAWT.java in
Classpath CVS (gnu/java/awt/peer/gtk) which also show some simpler AWT
things (without setting the colors to all kind of interesting values, so
it looks more like your normal Gnome/Gtk+ applications).
