title: DefaultMessageListenerContainer concurrentConsumers
body: <p>I have a question about DefaultMessageListenerContainer with multiple concurrentConsumers, the container creates differents sessions for each consumer but the problem for me is that the container allow only one message listner instance shared between all consumers, like this i cannot receive many messages and treat them in parallel because each thread will wait for the listener to be available, it is not better to allow each concurrent Consumer to have an exclusive instance of message listener to treat message ?</p>
