Proxy Problem with WebSockets

[a-haroun]

• Bug exists Release Version 1.2.0 ( Master Branch)
  Hello everyone,

I want to use a proxy with websocket MQTT client but the programm does not take the http proxy into account and instead it tries to use a socks proxy. And even with a socks proxy i have the following error: java.net.SocketException: Malformed reply from SOCKS server : MqttException
Is this normal?

UPDATE:
We are able to use now an HTTP proxy by using a custom ConnectionFactory, but now we have an authentication problem even though i used an authenticator and the client is hanged!
This is the code:

class SocksSocketFactory extends SocketFactory {
	public Socket createSocket() throws IOException{
		final String username = "xxxxx";
		final String password = "xxxxx";
		
		Authenticator.setDefault(new Authenticator() {
			protected java.net.PasswordAuthentication getPasswordAuthentication() {
				return new PasswordAuthentication(username, password.toCharArray());
			}
		});
		System.setProperty("http.proxyHost", "proxy.enterprise.com");
		System.setProperty("http.proxyPort", "80");
		System.setProperty("http.proxyUser", username);
		System.setProperty("http.proxyPassword", password);
		
		InetSocketAddress httpProxy = new InetSocketAddress("proxy.enterprise.com", 80);
		Proxy proxy = new Proxy(Proxy.Type.HTTP, httpProxy);		
		Socket sock = new Socket(proxy);
		return sock;		
	}

Here is the network flow:

Thank you in advance,
Amir
