如何判断代码的哪一部分未终止？

Question

我正在运行以下代码，这些代码是从Siddhi样本中复制的。到达代码的最后一行时，Eclipse表示某些内容仍在运行。我该怎么知道它是什么并将其关闭？

请注意，我对如何追踪这样的问题比对这个特定情况更感兴趣，因为我和其他库一样。

SiddhiManager siddhiManager = new SiddhiManager();

String executionPlan = "@config(async = 'true')define stream cseEventStream (symbol string, price float, volume long);"
        + "@info(name = 'query1') from cseEventStream[volume < 150] select symbol,price insert into outputStream ;";

ExecutionPlanRuntime executionPlanRuntime = siddhiManager.createExecutionPlanRuntime(executionPlan);

executionPlanRuntime.addCallback("query1", new QueryCallback() {

        @Override
        public void receive(long timeStamp, Event[] inEvents,
                Event[] removeEvents) {
            StringBuilder sb = new StringBuilder();
            sb.append("Events{ @timeStamp = ").append(timeStamp).
                    append(", inEvents = ").append(Arrays.deepToString(inEvents)).
                    append(", RemoveEvents = ").append(Arrays.deepToString(removeEvents)).append(" }");
            System.out.println(sb.toString());

        }
});

executionPlanRuntime.start();   

InputHandler inputHandler = executionPlanRuntime.getInputHandler("cseEventStream");
inputHandler.send(new Object[]{"IBM", 700f, 100l});
inputHandler.send(new Object[]{"WSO2", 60.5f, 200l});
inputHandler.send(new Object[]{"GOOG", 50f, 30l});
inputHandler.send(new Object[]{"IBM", 76.6f, 400l});
inputHandler.send(new Object[]{"WSO2", 45.6f, 50l});
System.out.println("Done feeding events");
Thread.sleep(500);
executionPlanRuntime.shutdown();
siddhiManager.shutdown();
System.out.println("Shutdown");
