Hello,
     moving from ActiveMQ 5 to ActiveMQ Artemis I was investigating a test 
failure.
It looks like Artemis doesn't allow to intercept the LWT messages triggered by 
an MQTT connection.
I have both a ServerPlugin (ActiveMQServerPlugin implementation) and a 
SecurityPlugin (ActiveMQSecurityManager5 implementation) but I don't see any 
call to authorize method (ActiveMQSecurityManager5) and beforeSend method 
(ActiveMQServerPlugin).
If I'm not wrong and the message is not intercepted by these plugins there is 
also a security issue because both the LWT topic and the message are set by the 
client while connecting to the server so malicious messages to a not allowed 
(by ACLs) topics could be used.

Thanks in advance for your feedback.

Regards

Riccardo
