When I use APIKit router with a Rest(jersey) component, I am getting a exception( as below), this exception does not occur when I use a flow-ref instead of the API Router ( Inserted flow snippet below). Any clues ?

Message : No serializer found for class org.mule.module.jersey.MuleResponseWriter$1 and no properties discovered to create BeanSerializer (to avoid exception, disable SerializationConfig.Feature.FAIL_ON_EMPTY_BEANS) ) (org.codehaus.jackson.map.JsonMappingException)

Code : MULE_ERROR--2

I believe the class MuleResponseWriter has some fields which do not have public getters or setters.
