Mit Desai resolved HDFS-5836.
-----------------------------

    Resolution: Not A Problem

After spending some time, I noticed that the setupCluster() and shutdownCluster() were not being called properly while running the customized series to mimic Java7 issue.

Not failing when these functions are called properly.
Closing for now

> This is an intermittent failure. Seems like a JDK7 issue. I did some initial research and found that the test always fails when it runs the following tests in order.

> 	  testBlocksRemovedBeforeStandbyRestart
> 	  testSafeBlockTracking
> 	  testBlocksAddedWhileStandbyIsDown
