SSLContext sc = SSLContext.getInstance("TLSv1.2"); //$NON-NLS-1$
sc.init(null, null, new java.security.SecureRandom());
HttpsURLConnection con = (HttpsURLConnection) httpsURL.openConnection();
con.setSSLSocketFactory(sc.getSocketFactory());
Other way would be setting VM arg to the Java.
-Dhttps.protocols=TLSv1.1,TLSv1.2
