Currently adding PropertyChangeListeners to accessible objects of a newly opened window is done asynchronously in the EventQueueMonitor class. This bears the risk that at the time the initiallly focussed component processes its FOCUS_GAINED event, there is not yet a listener attached to its AccessibleContext, so the ACCESSIBLE_STATE_PROPERTY change event to FOCUSED will get lost.

As a result, the user won't be informed which object in a dialog has the keyboard focus until (s)he starts traveling around.

This applies to all Java applications.
