      Description

      The taskReportServer is stopped in the TaskTracker.close() method in a thread. The race condition is:
      1) TaskTracker.close() is invoked - this starts a thread to stop the taskReportServer
      2) TaskTracker.initialize is invoked - this tries to create a new taskReportServer
      Assume that the thread started to stop the taskReportServer gets to start its work after (2) above. The thread will end up stopping the newly created taskReportServer.
