      The CMISProducer creates a CMISSessionFacade (CMISProducer.getSessionFacade()), delegates the initialization of a session to the facade (CMISSessionFacade.initSession()) and stores the facade inside a member variable. The CMISSessionFacade creates a Session, tries to connect to the remote system and stores the created Session object inside a member variable. If the provided password for the remote system is wrong then at this point a CmisUnauthorizedException (basically a RuntimeException) is thrown.

      (org.apache.chemistry.opencmis.commons.exceptions.CmisUnauthorizedException: Unauthorized)

      This behavior is ok but the consequence is that a member variable inside the CMISSessionFacade (called "session") is still null.

      Camel caches the CMISProducer with its reference to CMISSessionFacade whose "session" is set to null. If you try to send something else via cmis then you get the NullPointerException as described above.
