[9] Review Request: 8031485 [macosx] Combo box consuming escape key events

[Petr Pchelko]

Hello, 

Please review the fix for the issue:
https://bugs.openjdk.java.net/browse/JDK-8031485
The fix is available at:
http://cr.openjdk.java.net/~pchelko/9/8031485/webrev.00/

We should not consume the ESC if the popup is not visible.

Thank you.
With best regards. Petr.
