Thanks its passing further but stucked at taskSummaryHandler.getResults()

// krisv is Product Planner
    public static List<TaskSummary> getTaskDetails(String userName) {
        List<TaskSummary> task1 = null;
        try {
            SystemEventListenerFactory.setSystemEventListener(new SystemEventListener());
            TaskClient taskClient = createTaskClient();
            // "krisv" executes
            BlockingTaskSummaryResponseHandler taskSummaryHandler = new BlockingTaskSummaryResponseHandler();
            taskClient.getTasksAssignedAsPotentialOwner(userName, "en-UK", taskSummaryHandler);
            if (taskSummaryHandler != null && taskSummaryHandler.getResults() != null
                    && taskSummaryHandler.getResults().size() > 0) {
                // task1 = taskSummaryHandler.getResults().get(0);
                task1 = taskSummaryHandler.getResults();
            }
            System.out.println("ProcessTest.getTaskDetails() task1:" + task1);

            System.out.println("ProcessTest.getTaskDetails() ksession:" + ksession);

        } catch (Exception e) {
            System.out.println("ProcessTest.getTaskDetails()() Exception");
            e.printStackTrace();
        }

        return task1;
    }

public List<TaskSummary> getResults() {
        // note that this method doesn't need to be synced because if waitTillDone returns true,
        // it means results is available 
        boolean done = waitTillDone(RESULTS_WAIT_TIME);

        if (!done) {
throw new RuntimeException("Timeout : unable to retrieve results");
        }

        return results;
    }
