Question

当我向嵌入式Jetty服务器添加两个连接器时，我既不能使用HTTP也不能使用HTTPS - 浏览器/卷曲只会被卡住。我用来创建嵌入式Jetty的代码大致如下（它基于这个例子 - http://self-learning-java-tutorial.blogspot.de/2015/10/jetty-configuring-many-connectors.html）：

HttpConfiguration httpConfiguration = new HttpConfiguration();
httpConfiguration.setRequestHeaderSize(requestHeaderSize);

ServerConnector httpConnector= new ServerConnector(server, 1, -1, new 
    HttpConnectionFactory(httpConfiguration));
httpConnector.setPort(getPort());
httpConnector.setReuseAddress(true);
httpConnector.setIdleTimeout(maxTimeout);
server.addConnector(httpConnector);

HttpConfiguration httpsConfiguration = new HttpConfiguration();
httpsConfiguration.setSecureScheme("https");
httpsConfiguration.setSecurePort(securePort);
httpsConfiguration.addCustomizer(new SecureRequestCustomizer());

ServerConnector sslConnector = new ServerConnector(server,
            new SslConnectionFactory(sslContextFactory, HttpVersion.HTTP_1_1.asString()),
            new HttpConnectionFactory(httpsConfiguration));
sslConnector.setPort(securePort);
sslConnector.setIdleTimeout(maxTimeout);
sslConnector.setReuseAddress(true);

server.addConnector(sslConnector);

ServletContextHandler servContext = new 
ServletContextHandler(ServletContextHandler.NO_SESSIONS);
servContext.setContextPath("/");
server.setHandler(servContext);
server.start();

我打开了org.eclipse.jetty中的调试日志，并在任何请求中得到以下内容：

 Selector loop woken up from select, 0/1 selected [] [io.ManagedSelector][jetty-default-3]
 Running action org.eclipse.jetty.io.ManagedSelector$Accept@4278b8a5 [][io.ManagedSelector] [jetty-default-3]
 Queued change org.eclipse.jetty.io.ManagedSelector$CreateEndPoint@535fb063 on org.eclipse.jetty.io.ManagedSelector@3959754c id=3 keys=2 selected=0 [] [io.ManagedSelector] [jetty-default-3]
 EatWhatYouKill@1289003f/org.eclipse.jetty.io.ManagedSelector$SelectorProducer@7ff1b622/PRODUCING/0/1->PRODUCING/0/1 PEC org.eclipse.jetty.io.ManagedSelector$CreateEndPoint@535fb063 [] [strategy.EatWhatYouKill] [jetty-default-3]
 Selector loop waiting on select [] [io.ManagedSelector] [jetty-default-3]

当只添加一个连接器时，一切都按预期工作。

P.S。所以问题"Selector loop waiting on select" when running multiple test cases which use wiremock stubs和Jetty+Jersey infinite loop with curl post query除了在9.3中修复的码头错误（我使用9.4.3）之外没有给出任何答案
