<AWT Dev> <Awt Dev> [9] Review Request for 8080395: consider making sun.awt.CausedFocusEvent functionality public

[Semyon Sadetsky]

Hello,

Please review fix for JDK9:

bug: https://bugs.openjdk.java.net/browse/JDK-8080395
webrev: http://cr.openjdk.java.net/~ssadetsky/8080395/webrev.00/

This fix moves the caused property to java.awt.event.FocusEvent to make 
it public. The sun.awt.CausedFocusEvent class is removed as unnecessary.
The API change was approved http://ccc.us.oracle.com/8080395.
