websocket 限制QPS有效，但限制线程数无效

sentinel version : 1.3.0-GA

代码如下

@ServerEndpoint("/websocket/test/{requestId}") public class TestWebSocket {

private static final Logger logger = LoggerFactory.getLogger(TestWebSocket.class);

static {
    initFlowRules();
}

@OnOpen
public void OnOpen(@PathParam(value="requestId") String requestId, Session session) {

    Entry entry = null;
    try {
        entry = SphU.entry("HelloWorld");
        System.out.println("hello world");
    } catch (BlockException e1) {
        System.out.println("block!");
    } finally {
        if (entry != null) {
            entry.exit();
        }
    }
}

/**
 * 连接关闭调用的方法
 */
@OnClose
public void onClose(Session session) {
    logger.info("close:{}", session.getId());
}

/**
 * 收到客户端消息后调用的方法
 *
 * @param message 客户端发送过来的消息
 * @param session 可选的参数
 * @throws InterruptedException
 */
@OnMessage
public void onMessage(String message, Session session) {

}

/**
 * 发生错误时调用
 *
 * @param session
 * @param error
 */
@OnError
public void onError(Session session, Throwable error) {
    LoggerUtil.warn(logger, error, "websocket onError,sessionId={},status={}", session.getId(), session.isOpen());
}

private static void initFlowRules(){

    List<FlowRule> rules = new ArrayList<FlowRule>();
    FlowRule rule1 = new FlowRule();
    rule1.setResource("HelloWorld");
    rule1.setCount(20);
    rule1.setGrade(RuleConstant.FLOW_GRADE_THREAD);
    rule1.setLimitApp("default");

    rules.add(rule1);
    FlowRuleManager.loadRules(rules);
}

}
