Bug in key input routines in Java/OS X? Advice most appreciated!

The following little bit of code basically sets up a Panel as its own
key listener, and reports when key pressed/typed/released events
are being fired. It works perfectly well for every key on the keyboard
_except_ the Control key--which does work under Windows. (Actually,
the tab key is also nonfunctional, but I believe that has something
to do with the fact that I have not correctly taken complete management
of the focus--so I'm not too worried about that.) But the control key
should certainly be causing these events (and I need to monitor
them), so any feedback as to why this isn't working would be most
appreciated.

Thanks,
Ken McDonald
