<Swing Dev> [12] RFR JDK-8196097: javax/swing/JPopupMenu/6675802/bug6675802.java fails

[Prasanta Sadhukhan]

Hi All,

Please review a test fix for jdk12
Bug: https://bugs.openjdk.java.net/browse/JDK-8196097
webrev: http://cr.openjdk.java.net/~psadhukhan/8196097/webrev/

The test sometimes fails due to paint operation not being executed 
properly when run in group as the test always passes if run in 
standalone mode.
This is probably due to fact the swing component is not called from EDT.
Proposed fix is to make sure JPopupMenu is called from EDT.

Regards
Prasanta
