javax.net.ssl.SSLHandshakeException: "Remote host closed connection during handshake" opening an HTTPS page with HTMLUnit


I'm trying to fetch the HTTPS page https://portal.mvp.bafin.de/database/AnteileInfo/ using HTML Unit 2.23 under Java 7, Ubuntu Linux.

The following code worked until some days ago, but now I receive the exception reported below.

The problem should be related to the type of security certificates used, but nothing changes executing the code with the vm option "-Dhttps.protocols=TLSv1.1,TLSv1.2" as I read here

The code:

import java.io.IOException;
import java.net.MalformedURLException;

import com.gargoylesoftware.htmlunit.FailingHttpStatusCodeException;
import com.gargoylesoftware.htmlunit.WebClient;
import com.gargoylesoftware.htmlunit.html.HtmlPage;

public class SSLTest {

    public static void main(String[] args) throws FailingHttpStatusCodeException, MalformedURLException, IOException {
        final String URL = "https://portal.mvp.bafin.de/database/AnteileInfo/";
        final WebClient wc = new WebClient();
        // the code should be ok without the following line,
        // but even with it, it doesn't work
        // wc.getOptions().setSSLClientProtocols(new String[]{"TLSv1.1","TLSv1.2"});
        final HtmlPage mainPage = wc.getPage(URL);
    }
}

The exception is the following: Remote host closed connection during handshake

if uncomment the following line

wc.getOptions().setSSLClientProtocols(new String[]{"TLSv1.1","TLSv1.2"});

I get the exception below, which gives a slightly different message: fatal alert: handshake_failure

Any suggestion?


Solution

  • The problem was solved upgrading to Java 8, as haihui said in a comment (but I had just upgraded before that comment).

    I upgraded to Java 8 after reading Oracle's blog about HTTPS debugging and copying the JCE files suggested there in the $JAVA_HOME/lib/security (nothing changed).

    I decided to upgrade to java 8 after I saw this site about SSL Site debugging couldn't connect using java 7 too.

    During debugging I added this to the JRE arguments

    -Djavax.net.debug=all
    

    to see what's going on.
