KeyboardFocusManager.setCurrentKeyboardFocusManager() breaks focus

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?

I just ran into this problem as well. While developing a custom KeyboardFocusManager I noticed that even calling:

KeyboardFocusManager.setCurrentKeyboardFocusManager(new DefaultKeyboardFocusManager());

would change the behavior.

It appears that some early initialization was taking place, and the fix in my case was to set the KeyboardFocusManager before I showed any UI resources. I did this at the top of my application's main() function, and then the KeyboardFocusMangers worked as expected (both the default and my custom one).

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

If you need more help post your SSCCE.
