Hi Phil,

Thanks for your inputs.
Please find updated webrev for review:
http://cr.openjdk.java.net/~jdv/8233696/webrev.03/ <http://cr.openjdk.java.net/~jdv/8233696/webrev.03/>

Internal Test CI is green with latest change.

>> If test behavior has to be that it should fail when CAPS_LOCK is on then there is no need to change individual test cases where we are verifying alphabets.
>> There are only 2 regression tests which try to change locking state of CAPS_LOCK:
>> java\awt\Toolkit\LockingKeyStateTest\LockingKeyStateTest.java
>> java\awt\Toolkit\Headless\HeadlessToolkit.java
>> In case of HeadlessToolkit.java we expect to not get access to LockingState of the key so there is no need to update the code here. In case of LockingKeyState, I have added finally block to make sure that we restore key state in all cases.
