Supported SSL protocols with HttpRouter in SOA-P 5

Issue

• We currently use EasySSLProtocolSocketFactory to connect to a load balanced web service using HttpRouter.
• Unfortunately the connection is not very reliable and we need to debug from SOA-P. So far this has included switching on javax.net.debug=all as well as Apache Commons HTTP wire logging.
• When verbose logging is switched on, I can see that TLSv1 is the protocol that is being used. I've tried setting https.protocols=SSLv3 to force a different version of SSL to be used, however the logs still seemed to indicate that TLSv1 was being used.
• Could you provide the list of supported protocols by SOA-P and how they can be configured?
