{code}
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.
