[jira] [Created] (BEAM-1977) PubsubIO fails with NPE on ACK when running locally

Keith Berkoben created BEAM-1977:
------------------------------------

             Summary: PubsubIO fails with NPE on ACK when running locally
                 Key: BEAM-1977
                 URL: https://issues.apache.org/jira/browse/BEAM-1977
             Project: Beam
          Issue Type: Bug
          Components: sdk-java-core
    Affects Versions: 0.6.0
            Reporter: Keith Berkoben
            Assignee: Davor Bonaci


When running a PubsubIO-fed pipeline on a local machine, the pipeline runs for 10sec and then fails with a NPE (I'd guess when trying to ACK messages?). 

Logs confirm I am successfully reading messages and writing them out to pubsubIO, at least for a while.
