>How do you perceive that the JmsComponent / ActiveMQ component should figure out the query parameter is for a custom QueryBasedSubscriptionRecoveryPolicy ? There are a zillion options in ActiveMQ and not all is possible to compute from an uri string where they actually should be used. I think to remedy they there need to be more prefixes, so query would have to be prefixed with something that ties it to recoveryPolicy, so maybe? ?recovery.policy.queue=XXXX > However, there are also other uri paramters that activemq will process that > the jms/activemq components won't let thru.
