In your processor, since you are requesting the object contained in the message body as a particular type, it is possible for the value to be null if that is not the type that is actually on the body. Would you be able to verify the object type after the unmarshall.? You can do this in your processor by getting the Object on the message without a type (message.getIn().getBody() and checking the type.
