Wondering if this could be backported to 7.1. From https://issues.apache.org/jira/browse/ARTEMIS-1598 :

We are using a keycloak sasl authentication plugin in artemis to authenticate and authorize connections established outwards as well as incoming connections.

However, as the SslHandler is used in some cases to fetch the certificates of the peer, the handler is looked up by the name "ssl". This only works for incoming connections, since the NettyAcceptor uses addLast("ssl", sslhandler), but the NettyConnector uses addLast(sslHandler). This causes the lookup to fail.
