Stefan Richter commented on FLINK-6471:
---------------------------------------
Thanks for reporting this problem.
This is cause by a problem that I fixed in `BlockerCheckpointStreamFactory`.
However, it seems like for unknown reason (probably a move refactoring + merge)
this class existed twice, with all duplicated code. I will delete the copy and
just use the one, correct implementation everywhere.
