JComboBox Popup disappears immediately when clicking on a certain region

FULL PRODUCT VERSION :


A DESCRIPTION OF THE PROBLEM :
A JComboBox popup disappears immediately when clicking on the bottommost or rightmost line of the comboBox.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
The issue can be easily reproduced when the Metal Look And Feel is set. Simply click on the bottommost or rightmost line of a JComboBox. As soon as the mouse button is released the popup disappears. It's best reproducible with a non-editable comboBox - however, editable comboBoxes are affected too.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The JComboBox popup should appear and stay open when the mouse button is released.
ACTUAL -
The popup window is immediately closed as sson as the mouse button is released

REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
A workaround is pretty hard to implement. The issue is caused by a wrong area check in javax.swing.plaf.basic.BasicComboPopup$Handler.mouseReleased(...)

Unfortunately the rectangle size is not correctly set:
  Rectangle bounds = new Rectangle( 0, 0, size.width - 1, size.height - 1 );

The issue can be easily fixed by removing the "-1" value just like below.
  Rectangle bounds = new Rectangle( 0, 0, size.width, size.height);
