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.
