SSL套接字隧道握手异常

Question

所以我要创建一个tcp代理服务器的套接字，然后在顶部放置一个SSL套接字以连接到端点。与代理的握手很好，当我调用doSSLHandshake（tunnel，host，port）;我得到异常捕获：无法识别的SSL消息，纯文本连接？

我握手正确吗？我什么时候将邮件发送到服务器？

TrustManager trustManager = new AllTrustManager();
    SSLSocketFactory factory = (SSLSocketFactory) SSLSocketFactory
            .getDefault();

try {

        StartTLSFactory startTlsFatory = new StartTLSFactory(trustManager);

        Socket tunnel = startTlsFatory.createSslSocket(tunnelHost, tunnelPort);
        System.out.println("handshake with tunnel created");    
        SSLSocket socket = (SSLSocket) factory.createSocket(tunnel, host,
                port, true);

        /*
         * register a callback for handshaking completion event
         */
        socket.addHandshakeCompletedListener(
            new HandshakeCompletedListener() {
                public void handshakeCompleted(

                    System.out.println("Handshake finished!");
