A DESCRIPTION OF THE PROBLEM :
I have a program performing several tasks when the main frame is disposed. In addition I would like to manage correctly all events such as SIGINT, user end session (WM_QUERYENDSESSION), but it seems that we can't call the dispose method on a JFrame in a shutdown hook (it runs perfectly on Linux but blocks on Windows).


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
 to see easily the problem, run the code on a command line and perform a Ctrl+C (on Windows, the program never return)

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Either an exception (if it's an illegal operation), or windows behave like linux.
ACTUAL -
the program blocks under windows

ERROR MESSAGES/STACK TRACES THAT OCCUR :
no error message

REPRODUCIBILITY :
This bug can be reproduced always.
