Buttons are incorrectly laid out in GridLayout in Solaris for Jdk7
and events are not triggered when clicking on the corners of the buttons
when the vertical and horizontal gap is given

The attached tests fails on solaris and passes in linux.
Tested with build 1.7.0 b43 and b42 on solaris sparc 10 and Opensolaris where it fails
The test passes with 6u10, 6u12 and 1.6.0
Also fails in Windows

Steps to Reproduce:

Run the attached testcases (where hg and vg is the horizontal and vertical gap resp)
1. java ChangeGridsTest -hg 20 -vg 20
2. java GridLayoutTest -hg 20 -vg 20

Fails on the Ubuntu, RHEL5.
