ActiveMQ provided a way for the administrator to add a customer definition of an SSLContext to the server configuration. It was therefore possible to do custom validation of client certificates by, for example, associating a custom X509TrustManager to the SSLContext.

Artemis provides no comparable way to do this. To provide a comparable facility, we need to allow plugins access to the Netty transport layer, or otherwise to allow similar, protocol-level configurability.
