Ufuk Celebi resolved FLINK-2599. -------------------------------- Resolution: Cannot Reproduce Fixed the NPE via ac9a911. The NPE is a follow up issue. The main problem of Akka not starting up in the expected time is not reproducible and a general test hick up. I don't think that there is anything we can do about this for this specific test case. That's why I'm closing it. If you like, you can open a general test instability issue where we track this start up timeouts and discuss whether we can do something about it. > Failing Test: SlotCountExceedingParallelismTest > ----------------------------------------------- > > Key: FLINK-2599 > URL: https://issues.apache.org/jira/browse/FLINK-2599 > Project: Flink > Issue Type: Bug > Components: Tests > Reporter: Matthias J.
