Description
How to reproduce:

1. Compile and run the attached program.
2. Click on either of the two buttons.  This will bring up an InputMethodWindow
3. Click on the InputMethodWindow.  Then a focus lost event for the main window is printed out, saying that the getOppositeComponent returns null.

Expected result: At 3, return a non-null component that would receive the focus.
