Nope, with Camel v.1.5.0 it is the same. It is not an error in the logger,
the problem is in the JBI component (or how I am using it). If I send the
body to the logger directly from("jbi:endpoint....") or send to one of my
own components, I get a null object. This is the same whether or not I try
to unmarshal the message from the JBI endpoint.
