springfox: Groovy metaClass not ignored when model is built for deserialization

    @RequestMapping(value = "/myresource", method = RequestMethod.GET)
    MyResource get() {
    }

    @RequestMapping(value = "/myresource", method = RequestMethod.POST)
    MyResource save(@Valid @RequestBody MyResource myResource) {
    }

When I have only “get”, in my controller - MyResource does not have metaClass. As soon as I add “save”, metaClass appears in both calls.

Tracked to this code in BeanModelPropertyProvider:

  private BeanDescription beanDescription(ResolvedType type, ModelContext context) {
    if (context.isReturnType()) {
      SerializationConfig serializationConfig = objectMapper.getSerializationConfig();
      return serializationConfig.introspect(TypeFactory.defaultInstance()
          .constructType(type.getErasedType()));
    } else {
      DeserializationConfig serializationConfig = objectMapper.getDeserializationConfig();
      return serializationConfig.introspect(TypeFactory.defaultInstance()
          .constructType(type.getErasedType()));
    }
  }

In both cases introspect returns metaClass description
