Hi,

                Please review fix for JDK9,

                Bug: https://bugs.openjdk.java.net/browse/JDK-8155742

                Webrev: http://cr.openjdk.java.net/~arapte/8155742/webrev.00/

 

 

Issue:

                robot.keyPress(KeyEvent.VK_ALT_GRAPH) throws 
java.lang.IllegalArgumentException in windows

 

Cause:

                KeyEvent .VK_ALT_GRAPH is not supported by Robot.

 

Fix:

                Added VK_ALT_GRAPH key support under Robot for Windows.

VK_RMENU is an extended key, hence added flag KEYEVENTF_EXTENDEDKEY while 
calling keybd_event.

Doc: keybd_event()    
https://msdn.microsoft.com/en-us/library/windows/desktop/ms646304(v=vs.85).aspx

 

 

Verification:

                The change is specific to extended, VK_RMENU key.

                Hence existing robot behavior does get affected & no tests 
should fail.

 

                Verified by executing regression & JCK tests of Event, Robot, 
Keyboard.

                No existing test fails due to this change.

 

 

 

Regards,

Ambarish
