Steps to Reproduce:

1) Launch SwingSet2 demo.
2) Do Alt+l to open the "Look & Feel" menu.
3) From this menu, select a L&F other that the existing L&F of the SwingSet window.
4) Now do Alt+f to open the "File" menu.
Notice that the File menu fails to open. In fact it is not possible to open any menu using Alt+Mnemonic feature now. Whereas if you try to open these menu using this feature before changing the L&F, they opens.

This problem occurs on all the platforms.
