SSLHandshakeException SSLProtocolException with Android 6 (marshmallow)

问题

I've an app that communicates with a server through an SSLSocket. From Android 6 I receive a SSLHandshakeException

javax.net.ssl.SSLHandshakeException: Handshake failed

And in the server side:

 javax.net.ssl.SSLHandshakeException: no cipher suites in common

This happens only with Android 6, it seems there is something different in the chiper suites

I'm pasting the Server and client code for better troubleshooting

Server code:

ServerSocket server = null;
Socket socket=null;
SSLContext ctx;
KeyManagerFactory kmf;
KeyStore ks;
try{
     char[] passphrase = "password".toCharArray();
     String keyfile = "keyName";
     ctx = SSLContext.getInstance("TLS");
     kmf = KeyManagerFactory.getInstance("SunX509");
     ks = KeyStore.getInstance("JKS");
     ks.load(new FileInputStream(keyfile), passphrase);
     kmf.init(ks, passphrase);
     ctx.init(kmf.getKeyManagers(), null, null);
     ServerSocketFactory ssf = ctx.getServerSocketFactory();
     server = ssf.createServerSocket(port);
}catch (IOException e){
     e.printStackTrace();
}               
while (true) {              
     socket = server.accept();
     new Thread(new WorkerThread(socket));                

}

Android code:

  Socket clientSocket = null;
        KeyStore store = KeyStore.getInstance("BKS");
        InputStream in2 = ctx.getResources().openRawResource(
                R.raw.server);
        store.load(in2, "password".toCharArray());

        TrustManagerFactory tmf = TrustManagerFactory
                .getInstance(KeyManagerFactory.getDefaultAlgorithm());
        tmf.init(store);
        SSLContext sslcontext = SSLContext.getInstance("SSL");
        sslcontext.init(null, tmf.getTrustManagers(),
                new SecureRandom());
        SSLSocketFactory sslsocketfactory = sslcontext
                .getSocketFactory();
        clientSocket = (SSLSocket) sslsocketfactory.createSocket(
                Constants.SERVER_HOST, port);
        ObjectInputStream obi = new ObjectInputStream(
                clientSocket.getInputStream());
        ObjectOutputStream obs = new ObjectOutputStream(
                clientSocket.getOutputStream());

        obs.writeObject("text");
        obs.flush();

Any hint?
