Run the test java/awt/event/KeyEvent/AltCharAcceleratorTest/AltCharAcceleratorTest.java on OS X with JDK9 b120. It fails consistently with "Actions not performed".

Note that it fails also with b119 but pass consistently with b111, so regression is not in b120.
I also built and tried a current state of JDK9/client repository on Jun 1-st but it still failed.

Test pass with b120 on Linux.
