------------------------------------------------------------------

Artemis could certainly upgrade Netty versions, but without a reproducer there's no way for
the person doing the upgrade to verify the upgrade solved the problem and therefore justify
the upgrade is necessary. {{io.netty.handler.ssl.SslHandler}} has 3 commits since 4.1.22.Final
(which Artemis is currently using):
* https://github.com/netty/netty/commit/bf8cac4939ebad0756e39ad82c756bccea9c650a#diff-2fe7b22a8d650f1ea0bf56a809c061f9
* https://github.com/netty/netty/commit/978a46cc0a5242702f248842f6feb97b8fbe0123#diff-2fe7b22a8d650f1ea0bf56a809c061f9
* https://github.com/netty/netty/commit/268b901844c620337bc11ae82e99163a1781b96c#diff-2fe7b22a8d650f1ea0bf56a809c061f9

However, none of these appear to be related to the NPE you're hitting.

Just in case an upgrade might fix the problem could upgrade locally and attempt to reproduce
the issue using your test?
