> I wish to use SimpleMessageListenerContainer in transacted mode with multiple consumers. 
> But org.apache.camel.component.jms.JmsEndpoint line 224 is giving the listenerContainer a custom TaskExecutor, causing SimpleMessageListenerContainer to fail if sessionTransacted=true and concurrentConsumers>1. The custom taskExecutor causes JMS session commit to be called by the wrong thread randomly and fails.
> Can we update JmsEndpoint to not set taskExecutor just for SimpleMessageListenerContainer? I've tested this by overriding the lib and it works well with sessionTransacted=true and concurrentConsumers>1 (Solace broker). SimpleMessageListenerContainer has many benefits like true event driven over the default polling listenerContainer. Will be great to get it properly supported.
