      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:
