[Sergey Bylokhov]

Hello.
Please review the fix for jdk9.
The updated test does not take into account rounded corners of decorated 
window, and sometimes overlap with the Dock. The test is moved to the 
open ws.

Bug: https://bugs.openjdk.java.net/browse/JDK-7131835
The new test: http://cr.openjdk.java.net/~serb/7131835/webrev.00
Only useful changes for convenience:
