I use BlockingTaskSummaryResponseHandler to handler the query result,and this is my source code:
……………………………………………………………………………………………………………………………………………………
BlockingTaskSummaryResponseHandler taskSummaryResponseHandler = new BlockingTaskSummaryResponseHandler();
client.getTasksAssignedAsPotentialOwner("employee", "en-UK", taskSummaryResponseHandler);
List<TaskSummary> allTasks = taskSummaryResponseHandler.getResults();
…………………………………………………………………………………………………………………………………………………………………………
However,if i run this code frequently，exception below will occure:
