Hi,

I have an exception that always occur whenever the line of code highlighted in red is invoked:

  BlockingTaskSummaryResponseHandler responseHandler = new BlockingTaskSummaryResponseHandler();
                              responseHandler.waitTillDone(5000); 
                              jbpmUtil.getMinaClient().getTasksAssignedAsPotentialOwner(
                                                  taskOwner, "en-UK", responseHandler);
                              List<TaskSummary> results = responseHandler.getResults();


Here's the logs:
