FULL PRODUCT VERSION :
Discovered: 1.8.0_51
Also happens on: 1.8.0_05

ADDITIONAL OS VERSION INFORMATION :
OS 10.10.4

A DESCRIPTION OF THE PROBLEM :
If the application has a default menu and wants to use QuitStrategy.CLOSE_ALL_WINDOWS, all windows are closed, but AWT never exits.



STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run the provided program.
Select Quit from the application menu.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
I expect the application to quit.

Although in the normal situation, closing the last window *should not* close a Mac application, the default menu bar should be treated as a window for this purpose, though it does not appear in the list of windows returned from static methods on Window.
ACTUAL -
The application does not quit, although the window is closed as expected.

REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
The workarounds:

(a) avoid CLOSE_ALL_WINDOWS
Unfortunately, using QuitStrategy.SYSTEM_EXIT_0 results in other problems - now the EDT will be forcibly killed, despite important tasks being submitted to it which should be executed before shutting down.

(b) avoid setting a default menu bar
Not using the default menu bar is not really a good idea either, as this reduces native integration.

I will probably have to try some kind of workaround where we use SYSTEM_EXIT_0 but delay the call to performQuit() by calling that from another invokeLater. Piling up multiple calls to invokeLater has a habit of working and then breaking in a later release, however.
