9 is affected, the fix with regression wasn't synchronized with master yet.

8u60-defer-request: This is not critical regression introduced in 8u60 by JDK-8129788 fix. Fullscreen is not necessary to change display mode and this check may be removed. Proposed to target to 8u66.

This is the regression of JDK-8129788. Actually fullscreen is not necessary to change display mode and this check may be removed.

what is a connection to 8u60 back port: JDK-8129788 ?

Alexander, please fix it for 8u-dev (8u66)
