> An exception will be thrown when expanding an inline entity which is a one-to-many relationship to the entity itself.
> My entity model:
> @EdmEntityType
> @EdmEntitySet(name="Manufacturers")
> public class Manufacturer {
>        @EdmKey
>        @EdmProperty
>        private String id;
>        @EdmProperty
>        private String name;
>        @EdmProperty
>        private Calendar founded;
>        @EdmNavigationProperty
>        private List<Car> cars;
>        @EdmNavigationProperty
>        private List<Manufacturer> subManufacturers;
>        
> }
> Request:  http://localhost:8080/PqmODataExample/PqmODataExample.svc/Manufacturers('1')?$expand=SubManufacturers
> Response:
> {"error":{"code":null,"message":{"lang":"en","value":"Not implemented"}}}
> A workaround is to add toRole to the navigation property annotation as "@EdmNavigationProperty(toRole="r-manufacturers")".
