All Implemented Interfaces:

org.springframework.http.converter.GenericHttpMessageConverter<Object>, org.springframework.http.converter.HttpMessageConverter<Object>

public class JahiaMappingJackson2HttpMessageConverter
extends org.springframework.http.converter.json.MappingJackson2HttpMessageConverter

Own implementation of the JSON (using Jackson 2) message converter that handles correctly class loading. In case of an object, coming from a bundle, it looks up the corresponding message converter instance in OSGi and delegates the work to it. This implementation overrides only several methods from the parent, which are using the ObjectMapper instance, to be able to delegate to the corresponding message converter delegate (see PARAMETER_TYPES for the methods, we use for delegation).
