Subject Re: Hadoop 2.6.1 Release process thread

The HADOOP-10786 patch is compatible with JDK 6.  This was a point of
discussion during the original development of the patch.  If you'd like
full details, please see the comments there.  Like Akira, I also confirmed
that the new test works correctly when running with JDK 6.

Thanks!
