Juergen Hoeller opened SPR-14347 and commented
Since we're requiring Jackson 2.6+ as of Spring 4.3, we should finally override all of Jackson's factory methods in HandlerInstantiator, including non-abstract ones and recently introduced ones from Jackson 2.4 and 2.5: for ValueInstantiator, ObjectIdGenerator, ObjectIdResolver, PropertyNamingStrategy, Converter, VirtualBeanPropertyWriter.
