> 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.
