>> The issue was observed on the netbeans UI. 
>> The test below recreates a standalone test to mimic the failure reported in Netbeans in [JDK-7184401](https://bugs.openjdk.java.net/browse/JDK-7184401) and verifies that it is working as expected after it got fixed via [JDK-7189350](https://bugs.openjdk.java.net/browse/JDK-7189350))
>> 
>> The Test attempts to reproduce specific behavior of NetBeans at the certain toolbar creation stage. Widgets are created on EDT; Another code posts some events to them on EDT; From another thread some code calls explicitly edt.interrupt().
>> Before this got fixed, events from a second code got lost.
>> 
>> This review is for migrating tests from a closed test suite to open.
>> Testing:
>> 1.Tested the code on jdk7u6 to reproduce the issue - the UI hangs when run on this build.
>> 2. Tested the code on jdk7u361 b01 to validate the fix - the test passed.
>> 3.Mach5 Testing(40 times per platform) in macos x64, linux x64 and windows x64 - the .results are clean
