Rob Godfrey commented on QPID-7567:
-----------------------------------

Yeah - I basically decided that if you have multiple valid certificates for a 
server name then any one of them should do; and if you only want to send the 
one associated with a particular alias, you should not have added the other 
certificates into your store.  The alias is there only for the case where a 
valid certificate can't be found (for whatever reason).

> Enable SNI support for the Java Broker.
> We will need a X509ExtendedKeyManager implementation that gets the 
> SNIServerName from the SSL handshakes and then selects the most appropriate 
> certificate alias for the indicated hostname.
> I found the following example helpful:
> https://github.com/grahamedgecombe/netty-sni-example/blob/master/src/main/java/SniKeyManager.java
> https://docs.oracle.com/javase/8/docs/technotes/guides/security/enhancements-8.html
> This change requires Java 8, but it is probably possible to retain support 
> for Java 7 using reflection.
> It looks to me like the clients (Qpid JMS Client and Legacy) require no 
> changes. They both pass the hostname through to the SSLEngine, so the 
> SNIServerName should already be passed through. Client side support in Java 
> was added at Java 7.
