[8] Request for review: JDK-8013773: requestFocusInWindow to a disabled component prevents window of getting focused

[Anton V. Tarasov]

Hello,

Please, review the fix:
jira: https://jbs.oracle.com/bugs/browse/JDK-8013773
webrev: http://cr.openjdk.java.net/~ant/JDK-8013773/webrev.0

It resets the most recent focus owner in a window when DKFM rejects a 
FOCUS_GAINED event.
For more details, please read the jira comments.

Thanks,
Anton.
