<Swing Dev> JDK-8023043 : Clipboard.getAvailableDataFlavors: Comparison method violates contract

[Jason Mehrens]

Hello Swing-Dev,



Recently we have updated to JDK7u80 and have noticed a pattern of users generating the following error:



==================

java.lang.IllegalArgumentException: Comparison method violates its general contract!

=============



When I check the issue tracker http://bugs.java.com/view_bug.do?bug_id=8023043 shows as fixed in 7u60.  Did this get fixed in 7u60 through 7u80?   The stacktrace is a little different from that bug so should I file this as a new issue?



Thanks,



Jason
