Ted Yu commented on HBASE-16035:
--------------------------------

{code}
Failed tests: 
  TestReplicationKillMasterRSCompressedWithMultipleWAL>TestReplicationKillMasterRS.killOneMasterRS:34->TestReplicationKillRS.loadTableAndKillRS:88
Waited too much time for queueFailover replication. Waited 15112ms.
Flaked tests: 
{code}
The above is not related to the patch.

> Subtle problem in HBASE-15891:
> {code}try (A myA = new A(new B())){code}
> An exception thrown between B starting to open an A finishing initialization may not
result in B being closed. A safer syntax would be:
> {code}try(B myB = new B(); A myA = newA(myB)){code}
