      Description

      Reported by Robert Metzger:

      java.lang.NullPointerException
             at org.apache.flink.runtime.io.network.partition.consumer.LocalInputChannel.getNextBuffer(LocalInputChannel.java:185)
             at org.apache.flink.runtime.io.network.partition.consumer.SingleInputGate.getNextBufferOrEvent(SingleInputGate.java:444)
             at org.apache.flink.streaming.runtime.io.BarrierBuffer.getNextNonBlocked(BarrierBuffer.java:152)

             at java.lang.Thread.run(Thread.java:745)
      

      This is most likely caused by the result partition being released after the notifcations have happened.
