A DESCRIPTION OF THE PROBLEM :
When calling JMenu.doClick(int) on a JMenu that is part of a JPopupMenu, so having no JMenuBar at all the call to JMenu.buildMenuElementArray(JMenu leaf) hangs in an endless loop.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Create JPopupMenu, add JMenu into this and JMenuItem into the JMenu.

Now call doClick(10) on the JMenu.


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
No endless loop, maybe a click, maybe nothing, but no endless loop.


REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
Call MenuSelectionManager.defaultManager().setSelectedPath(me) in own code with an own created array like buildMenuElementArray() does but WITHOUT endless loop. Works!
