EXTRA RELEVANT SYSTEM CONFIGURATION :
Using XFree86-4.0.3-5 with Xfce as WindowManager

A DESCRIPTION OF THE PROBLEM :
When JPopupMenu.show(Component invoker, int x, int y) is
called the JPopupMenu instance is normally displayed at
position (x,y). However if the JPopupMenu is displayed and
then dismissed by calling JPopupMenu.setVisible(false) then
the next call to JPopupMenu.show() is ignored. If
JPopupMenu.show() is called again the menu is displayed as
normal.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Start attached java application (java PopupTest)
2. Left click near top left of window - JPopupMenu will be
displayed
3. Click on window, outside of JPopupMenu - JPopupMenu will
be dismissed
4. With keyboard focus on the window, press "g" on the
keyboard - JPopupMenu will be displayed near top left of window
5. With keyboard focus on the window, press "g" again on the
keyboard - JPopupMenu will be dismissed
6. Left click near top left of window - JPopupMenu will NOT
be displayed
7. Left click again near top left of window - JPopupMenu
will be displayed
8. Terminate java process

EXPECTED VERSUS ACTUAL BEHAVIOR :
In step 7, despite the JPopupMenu method being called, the
JPopupMenu component is not displayed. I would expect for it
to be displayed every time.
