I have a general question about this fix. Does it ever make sense for a server to call `SSLParameters.setEndpointIdentification` with a value of "HTTPS"? If not, then it probably makes sense to detect this error situation earlier and throw an Exception, preferably before the TLS handshake even starts. @bradfordwetmore Any thoughts on this one?
