I see another issue with using the CommandListenerInterface to start a process: the NewProcessInstanceCommand does not automatically signal the processInstance to advance the token. Thus, a second JMS message is required to signal the processInstance, but since the original message has no way to return a processInstanceId, there is no way to know which processInstance to signal. Also, the SignalCommand has a tokenId, but no processInstanceId (even if there were a way to return the processInstanceId).
