<AWT Dev> RFR: 8237243 [macOS] java/awt/event/KeyEvent/DisabledTargetF10/DisabledTargetF10.html fails

[Alexander Zuev]

Hello,

   please review my fix for issue.

   Bug: https://bugs.openjdk.java.net/browse/JDK-8237243
   Fix: http://cr.openjdk.java.net/~kizune/8237243/webrev/

   Test has been moved from closed part, cleaned up and marked linux only.
The initial fix that this regression test is for is viable only for XAWT 
toolkit so there is absolutely
no reason to test for it on any other platform.
