> This test case is failing. The expected order of locks is supposed to be T, 
> S, R. But upon closer inspection, it seems to be R,S,T. 
> I'm not much familiar with what these locks are and why the order is 
> important. Raising this jira so while I try to understand it all. Meanwhile, 
> if somebody can explain here, would be helpful.
