Hi Sergey,

Yes, similar changes have to be made in XToolkit also. What happens in XToolkit 
is that after the int overflow, when garbage width and height is passed to 
XCreateWindow, it handles it properly at its own end. So the test passes 
without any fix also. But the into overflow should not happen in the first 
place.

I have made changes in X11GraphicsConfig and XlibUtil Scaling functions and 
incorporated in the webrev. 
Webrev: 
http://cr.openjdk.java.net/~mhalder/pankaj/8145795/webrev.01/

I can see that XDragSourceContextPeer.java also contains ScaleUp and ScaleDown 
functions, but I don't see them being called from anywhere. So have not made 
changes in the same.

Regards,
Pankaj Bansal

Hi, Pankaj.
Can you please check that the same changes needs to be applied to the
XToolkit:

X11GraphicsConfig.scaleUp()
X11GraphicsConfig.scaleDown()
XlibUtil.scaleDown()
