I currently have an application that would make HTTP post request to a lot of URLs. Some of the connections are failing with the following exception.
from oracle (http://docs.oracle.com/javase/7/docs/technotes/guides/security/jsse/JSSERefGuide.html):
It enables TLS connections to virtual servers, in which multiple servers for different network names are hosted at a single underlying network address
If you disable jsse.enableSNIExtension you won't be able to connect to pages under a virtual server
