hacked to work with jdk7 with all tests ok
Added missing UISpecWindowPeerDecorator in the jdk6 specific sources.
Identical to jdk7 implementation expect for window type validation in show().
Changed implementation of ToolkitDelegate isModalExclusionTypeSupported and isModalityTypeSupported, which changed in JDK 1.6.0 update 38.
Correct modal type checking was implemented in JDK-2181173 - isModalityTypeSupported is not handled correctly
Fixed WindowInterceptor test to deal with localization in Swing UI labels.
If Locale is no en_US test will fail due to different label. Bug in JDK7 hides this bug.
