        Description

        FULL PRODUCT VERSION :
        The code is functional with the version of Java included with the current version of Netbeans.
        java version " 1.6.0_37 "
        Java(TM) SE Runtime Environment (build 1.6.0_37-b06-434-11M3909)
        JAva HotSpot(TM) 64-Bit Server VM (build 20.12-b01-434, mixed mode)

        The bug occurs with the most recent version of Java SE JDK for Mac OSX as of 1/16/2013 which I have uninstalled.
        The install file that has the bug is: jdk-7u11-macosx-x64.dmg

        The code is functional on Windows 7 64 Ultimate using both versions. My windows java version is:
        java version " 1.7.0.09 "
        java(TM) SE Runtime Environment (build 1.7.0.09-b05)
        Java HotSpot(TM) 64-Bit Server VM (build 23.5-b02, mixed mode)


        ADDITIONAL OS VERSION INFORMATION :
        Mac OS X 10.7.5
        This bug has been reproduced on 3 different mac systems though I am unsure of the other OS version numbers.

        A DESCRIPTION OF THE PROBLEM :
        Installing the current version of JDK causes key bindings to stop working in awt GraphicsEnvironment class using setFullScreenWindow method. I'm not sure if this is caused by an inability to focus on the fullscreen window, but I have tried all of the JComponent focus varients:
        WHEN_FOCUSED
        WHEN_IN_FOCUSED_WINDOW
        WHEN_ANCESTOR_OF_FOCUSED_COMPONENT

        I have also tried setExtendedState.


        REGRESSION. Last worked in version 6u31

        STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
        Run code on JDK 6 on Mac OSX and it will work.
        Install most recent JDK (7) on Mac OSX and it will not work.
        Remove JDK 7 and run code on JDK 6 and it will work again.


        EXPECTED VERSUS ACTUAL BEHAVIOR :
        EXPECTED -
        Running the code should put up a blank gray screen in fullscreen mode. Pressing ENTER should cause the program to output " Enter was pressed. " to stdout. Pressing ESCAPE should cause the program to output " Program Terminated by ESC Key " and close.
        ACTUAL -
        The ENTER and ESCAPE keys do nothing.

        ERROR MESSAGES/STACK TRACES THAT OCCUR :
        There is no error message associated with this problem.

        REPRODUCIBILITY :
        This bug can be reproduced always.
