JDK-6482575 - Leak in ImageIcon
Description
While investigating 6482575 (Leak in ImageIcon) I found that we're also leaking AppContexts from WWindowPeer.  A static Set named trackedAppContexts was added to fix 6503472 in b15.  AppContexts are added to this Set, but never removed.

As with 6482575, I used Chris Oliver's JApplication to reproduce this (along with a small application to show a frame).  See his "Poor Man's Multi-VM" blog entry for details:

EVALUATION we use set of AppContexts to track list of AppContexts for which we have registered KFM listener for activeWindow property. I think we could the set with one more key in AppContext's map which will report if we have added the listener or not (simple boolean).
