> I encountered a problem that happens if you run a route like
> from("servlet:///test").to("direct:cxfendpoint")
> Behind the direct endpoint there is a cxf jax-rs endpoint that is secured by spring-security.
If spring security denies access based on method annotations it throws an AccessDeniedException.
As JAX-RS does not handle it the exception hits the CamelDestination. There it is only logged
and swallowed. As the client then gets no error it tries to handle the reponse with jaxb which
fails. (See below)
