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

Hey Sean,

There is not much to share as its just a simple handshake :)

Anyway here is a reproducer:

https://github.com/normanmaurer/jdk_ssl_session_context_reproducer

It basically does nothing more then complete the handshake and then calling engine.getSession().getSessionContext() which will return null on the server side since JDK 14 (earlier versions work). I tested it with TLSv1.2 and TLSv1.3 and both times it produced the error on JDK 14.

Looks interesting Norman. Do you want to share some more details about the peculiarities of this handshake before considering a fully fledged testcase ?

regards,
Sean.

Hi there,

I am just about to add JDK14 to the test matrix for netty and think I found a regression. Before I will invest time to write a standalone reproducer please let me know if you think this is a regression or not. Basically after the handshake is complete SSLEngine.getSession().getSessionContext() returns null on the serverside when using JDK14. Running the same test with any previous version (JDK13 and earlier) doesn’t show the same result.

Does this sounds like a regression and if so should I provide a standalone reproducer here ?

Bye
Norman
