If you run the provided example and select "Re-build Popup Menu",
java dumps core.

I have tried several work-a-rounds, but I have not found any way to
remove sub-menu items from a popup-menu. Great if you could tell me
about any work-a-rounds...

We have waited for 1.1.2 to solve our popup-menu problems and were
glad so see that the previously reported bug (4039089) in this area is
solved now. Not so happy about this new one though... :-(
