ButtonDemo does not appear in SwingSet2 on Solaris and Windows starting with
the integration of build b16.

This error is output to the terminal running SwingSet2:
Error occurred loading demo: ButtonDemo

This bug is sporadic, happening about 50% of the time on Solaris 9
with both Gnome and CDE, with the b16 integration build.
