A DESCRIPTION OF THE PROBLEM :
If the mnemonic key is released before the ALT key, focus does not move to the combo box that is specified as the component for the labelFor property of a JLabel.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run the code given below. Select the ALT+C keyboard combination and release the ALT key before the C key. Focus will not move to the combo box. Try again, this time release the C before the ALT. In that case focus will move to the combo box.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Focus should move to the combo box regardless of whether the ALT key or the C key was released first.
ACTUAL -
Focus only moved to the combo box if the ALT key was released last.

REPRODUCIBILITY :
This bug can be reproduced always.
