Rakesh R commented on BOOKKEEPER-689:
-------------------------------------
[~fpj], I think NPE has no relation with test case failure mentioned in the
issue. I have seen few NPE in the attached logs and my above comment was
related to this. Anyway I'll also try to see the test case failure.
By seeing the following logs, the operation performed is:
1) Successfully connected to bookie
2) Tries to addEntry asynchronously.
3) At the sametime, closed the client. During channel closure,
PerChannelBookieClient sets channel=null and causing NPE for the above addEntry
2)
