A DESCRIPTION OF THE PROBLEM :
If a JPopupMenu is constructed with an icon and text items, the text items are located to the right of the right margin of the Icon item. The resulting popup menu is much wider than it needs to be, and text items are right-justified.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run the attached program. Click in the window area and observe the popup menu.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
A popup menu that is as wide as the icon.
ACTUAL -
A popup menu that is as wide as the icon+text width.

REPRODUCIBILITY :
This bug can be reproduced always.
