title: Unable to establish connection over TLS 1.2 on AIX 7.1/7.2
body: <p>How to enable communication over TLS1.2 on AIX 7.1 or 7.2 with IBM JDK 1.8 latest update?</p>
  
  <p>By default, the request is trying to establish a connection over TLSv1 even though TLS 1.2 is explicitly enabled on server as well as  on Java 8. The openssl command throws SSL handshake error. We tried with 2 versions of OpenSSL, 1.0.1e and 1.0.2k, but same behavior.</p>

  <p>It seems there is no cipher suites on common which can work for TLS 1.2.</p>
  
  <p>Also, is there any way to enable TLS 1.1 &amp; 1.2 in AIX? I have read few articles and got to know that these are not enabled  by default on AIX.</p>
