Java JPopupMenu doesn't work on OSX

Question

Using OSX 10.6.4 and Java 1.6.0_22, the JPopupMenu doesn't appear to work.
Simple code:
public static void main(String args[]){
final JPopupMenu popup = new JPopupMenu();
popup.add(new JMenuItem("first"));
JMenu sub = new JMenu("sub");
sub.add(new JMenuItem("next level"));
popup.add(sub);
popup.setVisible(true);
The 'first' item does respond if you click it, but the sub menu will never open, nor will the first item respond to a mouse over.
Any ideas? Help would be very much appreciated

Answer 1

Yep, go back to what works, appears to be the only real solution. But then you'd hardly be able to use Firefox as nothing is going to get fixed there only get broken.
What does not work is
# move, and resize of main window not allowed
# that include wiping out a lot of keyword shortcuts that do that
# various additional collateral damage
The solutions (work arounds) that I can best offer are clumsy but can be found in
