Yes — SSLParameters.setEndpointIdentificationAlgorithm("HTTPS") is available since Java 1.7. The only behavioral change is that connections where the server certificate doesn't match the target hostname will now be rejected. IOW, correct deployments are unaffected. |

If enabled the TLS hostname verification in Java sync client, how about adding it in aync client as well? |
