Being able to register listeners at runtime via the kafkaListenerEndpointRegistry is great. However when calling stop() and destroy() on MessageListenerContainer - this does not remove the bean from the kafkaListenerEndpointRegistry listenerContainers.

I cannot register, destroy - then re-register a container listener with the same ID without restarting the JVM. I receive an error 'Another endpoint is already registered with id' when calling kafkaListenerEndpointRegistry.registerListenerContainer.

Should I just not use the KafkaListenerEndpointRegistry if I want to dynamically register and unregister listeners at runtime?
