Sean Busbey commented on HBASE-21056:
-------------------------------------
this is a false positive. the code came in via HBASE-20894. In that issue,
precommit said findbugs was okay. the nightly run after the checkin failed to
run the jdk8-hadoop2 step, which is where we do findbugs. :( a couple of
evenings later the nightly run started doing that check again and this failure
started showing up (build #418).
