A DESCRIPTION OF THE PROBLEM :
Adding an icon to system tray and displaying a popup/message works in 1.6.0_23 but not in 1.7.0-ea.

Icon appears in system tray but the popup/message goes missing. EDT seems dead...? No menus...

ERROR MESSAGES/STACK TRACES THAT OCCUR :
None. Program just hangs.

REPRODUCIBILITY :
This bug can be reproduced always.
