There's a lengthy discussion about this at http://stackoverflow.com/questions/7615645/ssl-handshake-alert-unrecognized-name-error-since-upgrade-to-java-1-7-0
The cause of this is a "misconfigured" server which does not have the correct servername or serveralias. in case of apache it is missing the following configuration which solves it:

{code}
<VirtualHost mydomain.com:443>
  ServerName mydomain.com
  ServerAlias www.mydomain.com
{code}
If the above is missing from apache the server is warning the client while TLS/SSL handshaking that the requested name is not recognized (Level: Warning, Description: Unrecognized Name), Server mydomain.com. 
JDK7 (not JDK6!) then reacts to it with a "Fatal, Description: Unexpected Message". This is an additional check in JDK7 which they refuse to correct: "7127374 : JSSE creates SSLProtocolException on (common) warning: unrecognized_name for SNI" http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=7127374

The openshift-java-client currently sets this system property (https://github.com/adietish/openshift-java-client/blob/master/src/main/java/com/openshift/internal/client/httpclient/UrlConnectionHttpClient.java#L326) but it has no effect since it is not the first one to do SSL connections in Eclipse:
{code: title=UrlConnectionHttpClient}
// JDK7 bug workaround
System.setProperty(SYSPROP_ENABLE_SNI_EXTENSION, "false");
{code}

So the only fix that we currently have in Eclipse is to either connect to OpenShift Enterprise instances via IP-address or to turn SNI-checks off globally in eclipse.ini/jbdevstudio.ini:
{code}
-Djsse.enableSNIExtension=false
{code}
