Java SSLHandshakeException SSLProtocolException与Android 6（棉花糖）

我有一个通过SSLSocket与服务器通信的应用程序。 从Android 6我收到一个SSLHandshakeException

Android代码：

  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();

有什么提示吗？

根据这个：

似乎发生的是，注释性DH密码被丢弃。

因此，您不能再使用不在Android密钥库中的证书。

使用Nmap SSLtest或使用Nmap SSLtest测试服务器，并发布结果（支持的密码和协议）。此问题解决了吗？这个@Giuseppe有什么解决办法吗？

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));                

}
