Possible regression in JDK 14 related to SSLSessionContext / SSLSession on the server side

Hi Norman,

I've been able to run your test code and I can reproduce it. 
Interestingly enough, it appears to happen when 
-Djdk.tls.server.enableSessionTicketExtension=true, which is the default 
position.  With session tickets enabled, I would see the issue in TLS 
1.3 and 1.2 connections just as you did.  Setting the above property to 
false however allowed me to make successful connections.  Would you mind 
setting that property to false, just to make sure you and I see the same 
thing?

I did go back and run SSLServerSocket-based connections just to see if 
the session ticket settings had any impact on things, but they don't.  I 
can make connections to a socket based SSL server regardless of the 
property value on the server side.

Thanks,

--Jamil
