Request for approval for 7124310: [macosx] "opposite" seems always null in focus

[Leonid Romanov]

Hi,
This is a request to push the backport of 7124310 into jdk7u-dev. The fix was 
pushed into JDK 8 long time ago.

Bug: https://jbs.oracle.com/bugs/browse/JDK-7124310
Webrev: http://cr.openjdk.java.net/~leonidr/7124310/webrev.01/
JDK 8 changeset: http://hg.openjdk.java.net/jdk8/awt/jdk/rev/094c963dca1b

Thanks,
Leonid.
