>>> I tried to use jcr component as consumer, expecting jcr observation event listener like behavior, but I realized that it's not supported yet. The current jcr component supports producer only. So, I'm considering to implement JcrConsumer and possibly contribute it in a new CAMEL JIRA issue later.
