A DESCRIPTION OF THE PROBLEM :
When I create a subclass of PopupFactory and _override_ #getPopup(Component,
Component, int, int) of PopupFactory and use this subclass in a sandbox
environment, then the heavy weight Popups are not shown properly.
Medium weight and light weight Popups are shown without a problem.
When I do not override the #getPopup-method, everything seems to work fine.
This problem is not reproducible on Windows.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1) compile the test case.

2) run the test case with following command:

    java -Djava.security.manager Test

3) when the window is visible, move the mouse cursor
     over the button to display the tooltip.


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
A nice tooltip.
ACTUAL -
An empty window with no content. The window height grows when the heavy weight
Popup is displayed again.

REPRODUCIBILITY :
This bug can be reproduced always.
