Márton Balassi reopened FLINK-2464:
-----------------------------------

Thanks for the fix, [~StephanEwen]. Unfortunately I still see tests of the `flink-streaming-core` module fail due to a killed JVM post your commit. [1] 

I can also suspect that this is coming from either the `BarrierBufferTest` or the `BufferSpillerTest`, becuase after disabling them `flink-streaming-core` did not once fail on java 6 in 20 builds triggered on travis. [2] (Builds that still failed were due to the failures of the `StreamCheckpointingITCase` or the `PartitionedStateCheckpointingITCase` in `flink-tests`.)
