@John: GenericEntity is not abstract ;) Personally I use the public constructor to avoid to need to extend it in several places and ensure the dyncamic type is the one I expect whatever impl I use but it needs a Type implementation matching a generic type:
https://github.com/rmannibucau/rblog/blob/f23ec03261b5a6f42de50a9f3f7f083bcf85fc33/src/main/java/com/github/rmannibucau/rblog/jaxrs/reflect/CollectionType.java (side note: johnzon provide one implementatio as well which is built in in tomee) is a generic on then you can define the type you need as a constant ( https://github.com/rmannibucau/rblog/blob/f23ec03261b5a6f42de50a9f3f7f083bcf85fc33/src/main/java/com/github/rmannibucau/rblog/jaxrs/CategoryResource.java#L39) and finally use the GenericType directly ( https://github.com/rmannibucau/rblog/blob/f23ec03261b5a6f42de50a9f3f7f083bcf85fc33/src/main/java/com/github/rmannibucau/rblog/jaxrs/CategoryResource.java#L55) client or server side without extending it.
