Extended server_name (SNI Extension) not sent with jdk1.8.0 but send with jdk1.7.0

Question

I have implemented a JAX-WS client by using ApacheCXF (v3.0.4) and everything works successfully but the problem comes when I want to use a secure connection (SSL/TLS) with

Answer 1

As mentioned, the cause is related to the JDK bug where using setHostnameVerifier() breaks SNI (Extension server_name). https://bugs.openjdk.java.net/browse/JDK-8144566

Our workaround: After testing we found that setting a connection's SSLSocketFactory to just about anything from the default seems to fix the issue.

This does not work: HttpsURLConnection.setSSLSocketFactory((SSLSocketFactory) SSLSocketFactory.getDefault());

This does work: HttpsURLConnection.setSSLSocketFactory(new SSLSocketFactoryFacade());

So, to fix it for a JAX-WS client, you could do something like this: bindingProvider.getRequestContext().put("com.sun.xml.internal.ws.transport.https.client.SSLSocketFactory", new SSLSocketFactoryFacade());

Our SSLSocketFactory facade: (Note that it really doesn't do anything)

public class SSLSocketFactoryFacade extends SSLSocketFactory {

    SSLSocketFactory sslsf;

    public SSLSocketFactoryFacade() {
        sslsf = (SSLSocketFactory) SSLSocketFactory.getDefault();;
    }

    @Override
    public String[] getDefaultCipherSuites() {
        return sslsf.getDefaultCipherSuites();
    }

    @Override
    public String[] getSupportedCipherSuites() {
        return sslsf.getSupportedCipherSuites();
    }

    @Override
    public Socket createSocket(Socket socket, String s, int i, boolean b) throws IOException {
        return sslsf.createSocket(socket, s, i, b);
    }

    @Override
    public Socket createSocket(String s, int i) throws IOException, UnknownHostException {
        return sslsf.createSocket(s, i);
    }

    @Override
    public Socket createSocket(String s, int i, InetAddress inetAddress, int i1) throws IOException, UnknownHostException {
        return sslsf.createSocket(s, i, inetAddress, i1);
    }

    @Override
    public Socket createSocket(InetAddress inetAddress, int i) throws IOException {
        return createSocket(inetAddress, i);
    }

    @Override
    public Socket createSocket(InetAddress inetAddress, int i, InetAddress inetAddress1, int i1) throws IOException {
        return createSocket(inetAddress, i, inetAddress1, i1);
    }
}
