<AWT Dev> [9] Review Request: 8044516 [macosx] ScreenPopupFactory uses native method that could be avoided

[Petr Pchelko]

Hello, AWT Team.

Please review a simple cleanup fix for the issue:
https://bugs.openjdk.java.net/browse/JDK-8044516
The fix is available at:
http://cr.openjdk.java.net/~pchelko/9/8044516/webrev/

No need to go through native to call a method. Accessor pattern works 
fine here, so we can avoid loading a native library.

Thank you.
With best regards. Petr.
