Hello, Please review the fix http://cr.openjdk.java.net/~azvegint/jdk/9/8131752/00/ for the issue https://bugs.openjdk.java.net/browse/JDK-8131752
This fix simply restores fullscreen windows check. Actually fullscreen is not necessary to change display mode, but since I am planning to backport it to 8u66 it is too risky to change behavior. It should be reconsidered along with 8022810 [0].

-- Thanks, Alexander.
