> 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.
