on the topic uses the default subscription name which is the class name: org.apache.camel.component.jms.EndpointMessageListener.
>>> In the documentation on GitHub for Camel Version 2.24.1 it is written that the
subscriptionName can be used for shared subscription too.:
>>> subscriptionName (consumer)
>>> Set the name of a subscription to create. To be applied in case of a topic (pub-sub
domain) with a shared or durable subscription. The subscription name needs to be unique within
this client’s JMS client id. Default is the class name of the specified message listener.
Note: Only 1 concurrent consumer (which is the default of this message listener container)
is allowed for each subscription, except for a shared subscription (which requires JMS 2.0).

is durable (which I don't want to have):

a bug that the subscriptionName can only be used in combination with a durable subscription?
