Issue

When trying to configure JBoss Fuse to use a different JAAS configuration realm for the embedded ActiveMQ broker than the Karaf container, this configured security realm is ignored. The broker continues to use the security realm of the Karaf container called 'karaf'.

E.g. configuring etc/activemq.xml to

<plugins>
  <!-- changing realm name from default 'karaf' to 'mq' -->
  <jaasAuthenticationPlugin configuration="mq" />
</plugins>

the embedded ActiveMQ broker will still use the default 'karaf' authentication realm.

Trying to access the broker from a JMS client results in

User name admin or password is invalid.

although the right security credentials were submitted.
