-------------------------------------------------------------- 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: BEFORE RULEFLOW VARIABLE CHANGED recipient=gimeno.vallangca process:Sample
