------------------------------------------------
Oh, Thanks Sijie for the patch. I couldn't take a look (I was on leave).
Also I should have run the suit once. Since the changes are pretty straight
forward and had full confidence that tests will pass.
I remember surefire will fork separate JVM for each test. no?

> TestServers failed when running whole test. Because TestServers uses
> ServerStats instance directly. ServerStats is a static instance, which will
> be used across whole testing. so the numSuccessOps would not be zero, the
> assertion would fail.
> Same problem occurs in TestBKStats. TestBKStats doesn't fail because
> statistics is turned off by default. The value happened to be zero. But it
> still is not a good idea to use static instance during testing.
