Michael Han commented on ZOOKEEPER-2712:
----------------------------------------
[~rakeshr] Good job on hunting down the culprit of the race!
I am curious what exactly cause the races though - from the description it was
not very clear to me. Do you mind to elaborate a little bit with regards to
what code in test case that uses what function in the dependency library and
what the race condition is?
Regarding find bug warnings - I tried find bugs (3.0.1) locally and I also get
97 warnings. I suspect we did not get such warnings either because we did not
run find bugs at all for branch-3.4, or find bug version updates. I think we
should fix the warnings before releasing of 3.4.10, not sure if you agree with
this or not. Regardless of this, I think fixing findbug warning is out scope of
this particular JIRA and we could use another JIRA to track it (same for the
javadoc warnings).
