[8u40] Request for approval: JDK-8048887 SortingFocusTraversalPolicy throws IllegalArgumentException from the sort method

[Anton V. Tarasov]

Hello,

This is a direct [*] backport from jdk9 into jdk8u40 of the following fix:

bug: https://bugs.openjdk.java.net/browse/JDK-8048887
webrev: http://cr.openjdk.java.net/~ant/JDK-8048887/webrev.1

in jdk9: http://hg.openjdk.java.net/jdk9/client/jdk/rev/5a5ae13cbc66
review: http://mail.openjdk.java.net/pipermail/swing-dev/2014-July/003645.html

Thanks,
Anton.

[*] Except that I had to correct the @run line of the reg test with the right bugid.
