A DESCRIPTION OF THE PROBLEM :
Using a JButtons setMnemonic(int i), and setting the button to VK_F4 causes the letter 'S' in the JButton to be underlined. The tooltip text clearly says Alt-F4. The value for VK_F4 is 115, which happens to be the byte value for lowercase 'S'.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
run attached code

EXPECTED VERSUS ACTUAL BEHAVIOR :
nothing underlined?
  Tooltip text says "Shutdown Alt-F4"
S on shutdown is underlined.
  Tooltip text says "Shutdown Alt-F4"

REPRODUCIBILITY :
This bug can be reproduced always.
