The 2 failures are due to
1. TestTrackerDistributedCacheManager : This error seems unrelated to this patch. This patch doesn't change anything in DistributedCache. I checked the stack trace and found NPEs. I will look into it further.
2. TestTTMemoryReporting: This testcase got deleted and rewritten as part of this patch. We only need to delete the stray file.
I uploaded the patch only after test-patch and ant-tests passed. I am re-running them to make sure nothing changed after I generated the last patch.
