I should have been more clear about my exact setup. I am trying to create multiple consumers that either listen to a JMS queue or a JMS topic. Each consumer listening to a queue has no client ID as it is not needed. Each consumer listening to a topic has both a client ID (the same one for all consumers) and a subscription name (unique per consumer) configured.
The queues and topics are all hosted within an external application server that I am connecting to. All of this works perfectly until I try to change the subscription name of one of the topic consumers. I believe this issue stems from the fact that they are durable subscribers, which leads my application server to store them persistently. After changing the subscription name, the ActiveMQSession is aware of the fact that it has changed and I run into the second part of this if-statement because no short-circuiting occurs. https://github.com/apache/activemq-artemis/blob/98d792d135dacb8fc567bc514f42a40d91c0657b/artemis-jms-client/src/main/java/org/apache/activemq/artemis/jms/client/ActiveMQSession.java#L1002 I am trying to understand why the choice was made to have this `configurationManaged` property be nullable as it leads to an issue where the null value is attempted to be inverted which leads to an exception.
