JBoss mutual certificate authentication fails on SSL Handshake - ssl

Question

I followed all the steps in this blogpost http://virgo47.wordpress.com/2010/08/23/tomcat-web-application-with-ssl-client-certificates/ except for the fact that I'm using JBoss7.0.2 and not the 6.x version.
The goal is to ask any clients to provide a client certificate and achieve mutual authentication between the client and the server.
I have created a certification authority (CA) to sign the client and server certificates.
I have imported the server certificate into the keystore and added an HTTPS connector to the standalone.xml configuration file to serve HTTPS requests on the 8443 port.
I have imported the CA root certificate into the Certificate Manager under Authorities in client's Firefox.
Everything works fine and when I request https://localhost:8443 I get a page with a valid server certificate.
The problem is, when I import the client certificate into the Certificate Manager in Firefox and set the server configuration to verify client certificates (verify-client="true" in standalone.xml) I get a browser error:
Secure Connection Failed:
An error occurred during a connection to localhost:8443.
SSL peer cannot verify your certificate.
(Error code: ssl_error_bad_cert_alert)
while the jboss log on the server states:
11:01:31,142 DEBUG [org.apache.tomcat.util.net.JIoEndpoint] (http-localhost-127.0.0.1-8443-1) Handshake failed: java.io.IOException: SSL handshake failed. Ciper suite in SSL Session is SSL_NULL_WITH_NULL_NULL

Do you have any idea how to resolve this problem?

I'll be happy to provide other relevant information if needed.

You might want to give a try by adding cipher suite you your ssl connector:
<ssl name="ssl" key-alias="sercer" password="changeit" certificate-key-file="/usr/share/jboss7.0.2/standalone/configuration/certificates/keystore.jks" protocol="TLSv1" verify-client="true" ca-certificate-file="/usr/share/jboss7.0.2/standalone/configuration/certificates/cacerts.jks" cipher-suite="AES+RSA"/>
