KeyboardFocusManager.setCurrentKeyboardFocusManager() breaks focus

Question

I overrode DefaultKeyboardFocusManager to provide some special behavior for the Alt key. However, after setting this, I notice that hitting Tab on some of my text fields does not work.

I also experimented with even calling the following on the AWT, but this still exhibited the broken Tab behavior:

KeyboardFocusManager.setCurrentKeyboardFocusManager(new DefaultKeyboardFocusManager());

Why would setting the current keyboard focus manager have such bad effects?

You wrote some custom code and now you have problems? Just a guess here but maybe the problem is with your code?
