[jira] [Created] (BEAM-6561) WorkProgressUpdater synchronizes on java.util.concurrent classes

Kenneth Knowles created BEAM-6561:

             Summary: WorkProgressUpdater synchronizes on java.util.concurrent classes
                 Key: BEAM-6561
                 URL: https://issues.apache.org/jira/browse/BEAM-6561
             Project: Beam
          Issue Type: Bug
          Components: runner-dataflow
            Reporter: Kenneth Knowles


Findbugs caught this. There seems to be synchronization on variables where the classes themselves have their own mechanisms. If intended, it should be made more clear by simple mutexes.
