> There is a need to support XOAUTH2 authentication between two AMQP brokers, 
> as the existing mechanisms are not sufficiently secure for certain use cases. 
> Currently, Artemis does not support this authentication method on the client 
> side, and the SaslFactory implementation is both private and final, making it 
> impossible to extend.
> To address this, an XOAuth2SASLMechanism should be implemented within the 
> AMQPBrokerConnection class and integrated into the SaslFactory. The new SASL 
> mechanism should return its name as "XOAUTH2" and include the appropriate 
> authentication headers.
> A working example of this approach has been successfully tested with the 
> Solace broker:
> {code:java}
> @Override
> public byte[] getInitialResponse() {
>    String response = String.format("user=%s\u0001auth=Bearer %s\u0001\u0001", 
> userName, token);
>    return response.getBytes(StandardCharsets.UTF_8);
> }
> {code}
