JDK-6709453 - Screen flickers when a JFrame switches to fullscreen mode
Description
This issue is closely related to http://monaco.sfbay/detail.jsf?cr=6709453. 

I am tring to switch to fullscreen mode where the frame is already in full screen mode. Doing this the frame flickers like http://monaco.sfbay/detail.jsf?cr=6709453. 

Step to reproduce:-
-----------------------
Use the http://monaco.sfbay/detail.jsf?cr=6709453 testcase.
1) Run the attached program.
2) When the frame is visible. select fullscreen menu item. Observe that frame switch from normal to full screen. This solves the issue of http://monaco.sfbay/detail.jsf?cr=6709453
3) Once again select the fullscreen menuitem. Observe that frame flickers as if http://monaco.sfbay/detail.jsf?cr=6709453 is not fixed. If you see the same then the bug is reproduced.  

I tried the same scenario in jdk6 , it works fine.
Comments
EVALUATION An excessive flickering (more like activation-deactivation sequence with high speed) has observed with JDK7b104. The console says "focusLost-focusGained- focusLost-focusGained" in somewhat like infinite loop. Needs attentition. I'm using XP SP2.
