JDK-4980161 - REG:setting focusable window state to false makes the maximized frame resizable
Description
I have a non focusable frame, when i resize the frame i can see that frame icon goes over the minimize , maximize & close button. I can resize the frame to very small & infact we can make the frame to invisible on the frame by resizing. 

The same behaviour can be seen from 1.4.2 onwards till jdk1.6.0 b40 ( the build i had ). But some how the problem is not seen jdk1.6.0 b48 ( the build i had) to jdk1.7.0 b01, But the problem is seen from jdk1.7.0 b02 onwards. Hence this is a regression from jdk1.6 to jdk1.7 . The bug is not reproducable even jdk1.6.0 update releases , not only that http://monaco.sfbay/detail.jsf?cr=4980161 is also not seen. but the  http://monaco.sfbay/detail.jsf?cr=4980161 is once again seen from jdk1.7.0 b02 onwards. But it got fixed in jdk1.7.0_b17 pit build.

The bug is reproduce only when the frame is non-focusable. 

Step to reproduce:
------------------
1) Run the attached testcase.
	java WindowStateTest <0/1>
	0 - set focusable window state to true
	1 - set focusable window state to false

Pass "1" as the argument. 
2)A frame will be shown. 
3) Click on the maximize button , so that the frame is maximized.
4) Move the mouse to the right buttom of the frame & try resizing the frame. 
Observe that frame icon (java cup) is seen on the frame buttons & resizing it to further the frame is not seen on the screen. If you see the same then the bug is reproduced.

EVALUATION Removing the SWP_NOSENDCHANGING flag when invoking the ::SetWindowPos() Win32API function at AwtFrame::WmMouseMove() function seems to help. While this flag is set, Windows seems to not constrain the size of the window at all.

EVALUATION The strange thing is that I'm able to reproduce this bug with 6.0-b46 and at the same time see no fixes in 6.0-b47/48 that could affect the problem. In 7.0-b02 the "suspicious" fixes are 6355340 and 6399659, probably one of them caused the bug to reappear again.
