A DESCRIPTION OF THE PROBLEM :
  Toolkit.getScreenInsets(GraphicsConfiguration) returns incorrect results for a screen on which KDE doc is located, when there is a second screen with bigger height.

Screen configuration (typical setup for a notebook with external monitor attached):
+----------------------+ +---------------------------+
| | | |
| Screen 0: | | Screen 1: |
| 0, 0, 1280x960 | | 1280, 0, 1600, 1200 |
| | | |
+-----------------------+ | |
| KDE doc (h: 35) | | |
+-----------------------+ | |
                                     | |
                                    +---------------------------+

Expected insets for screen 0 are [0, 0, 0, 35], actual: [0, 0, 0, 275].

Supposedly, the problem was introduced in a course of fixing http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4737732.
