      Description

      At line 140:

              } else {
                ta = new TaskAttemptInfo(successful, type, false);
      

      There is no check for type against null.
      TaskAttemptInfo ctor deferences type:

        public TaskAttemptInfo(TaskAttempt ta, TaskType type, Boolean isRunning) {
          final TaskAttemptReport report = ta.getReport();
          this.type = type.toString();
