我有一个带有 sleep 方法的简单 REST 服务，该方法除了在指定的毫秒时间内睡眠之外不做任何事情，然后返回无内容响应。我的 RESTTest 类尝试首先调用http://localhost:8080/myapp/rest/sleep/7500（休眠 7.5 秒），但只等待 5 秒。5 秒后，它取消接收到的 Future（尝试取消挂起的请求）并调用http://localhost:8080/myapp/rest/sleep/5000（休眠 5 秒）并等待 5 秒。

public class RESTTest {
    private final Client client = ClientBuilder.newClient();
    private final ReentrantLock lock = new ReentrantLock();
    private final Condition responseReceived = lock.newCondition();

    public static void main(final String... arguments) {
        new RESTTest().listen(10000);
    }

    public void listen(final long time) {
        System.out.println("Listen for " + time + " ms.");
        Future<Response> _response =
            client.
                target("http://localhost:8080/myapp/rest/sleep/" + time)).
                request().
                async().
                    get(
                        new InvocationCallback<Response>() …
