FULL PRODUCT VERSION :
java version "1.7.0_45"
Java(TM) SE Runtime Environment (build 1.7.0_45-b18)
Java HotSpot(TM) 64-Bit Server VM (build 24.45-b08, mixed mode)

ADDITIONAL OS VERSION INFORMATION :
Mac OS X 10.7.5

EXTRA RELEVANT SYSTEM CONFIGURATION :
You will need SWT (3.7.2 or 4.3) libraries to run the executable test case. The test case calls SwingUtilities.invokeAndWait but the application in which the issue was originally faced exhibits same behavior with SwingUtilities.invokeLater.

A DESCRIPTION OF THE PROBLEM :
On Mac application calls to AWT frame object (Created using SWT_AWT bridge) methods do not return when called from AWT thread.

Same test case as well as the original application runs fine on Windows platform.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Please run the executable test case with needed SWT libraries

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Dialog should appear with a "Submit" button on top an AWT frame.
ACTUAL -
Application gets stuck while opening the dialogue.
