> JMS Connection Fails After JMS servers Change behind JNDI.
> Reproduce:
> # Define and enable JNDI Controller Service
> # Create a flow with ConsumeJMS or PublishJMS processors with controller
> service defined in #1.
> # Consume and publish at least one message to ensure the connectivity can be
> established.
> # Change JNDI configuration for the same connection factory to point to new
> JMS servers.
> # Stop JMS service on previous servers
> # Observe failure in ConsumeJMS/PublishJMS (Caused by:
> javax.jms.JMSException: Failed to connect to any server at:
> tcp://jms_server1:12345)
>
> Work Around:
> # Disable JNDI Controller Service
> # Enable JNDI Controller Service and dependent processors.
>
> Possible Issue/Fix:
> * AbstractJMSProcessor has a method "buildTargetResource", in which
> connection factory is instantiated and then cached in workerPool in onTrigger
> .
> * Issue: Once cached, it will be reused forever.
> * Fix: on connectivity failure there should be an attempt to rebuild the
> worker.
