Semen Boikov commented on IGNITE-1564:
--------------------------------------
Found bug in client reconnect handling which can cause NPE from the first
stacktrace in case when multiple clients try to reconnect at the same time.
Fixed it in branch ignite-1564, added more tests for this scenario, waiting for
TeamCity results.
Second stacktrace is for code from 1.3, this issue should be already fixed in
1.4.
