[8] Review request for 7124242 [macosx] Test doesn't work because of the frame round corners in the LaF

[Konstantin Shefov]

Could you please look at this test fix?

Webrev: http://cr.openjdk.java.net/~kshefov/7124242/webrev.00/

JFrame was undecorated to make test pass on MacOSX and Windows 7 with Aero.

Thanks,
Konstantin
