OpenAPI spec not generated correctly when JSR303 Bean Validation annotations used

[gbengataylor]

When a JSR303 annotation is used on the RequestBody of REST operation, the paths.{operation}.requestBody is not generated in the swagger documentation

This code was tested with OpenJDK Runtime Environment (build 1.8.0_161-b14) and Quarkus 0.14.0.

@Path("/fruits")
@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.APPLICATION_JSON)
public class FruitResource {

    private Set<Fruit> fruits = Collections.newSetFromMap(Collections.synchronizedMap(new LinkedHashMap<>()));

    public FruitResource() {
        fruits.add(new Fruit("Apple", "Winter fruit"));
        fruits.add(new Fruit("Pineapple", "Tropical fruit"));
    }

    @GET
    public Set<Fruit> list() {
        return fruits;
    }

    @POST
    public Set<Fruit> add(@Valid /* JSR Bean validation*/ Fruit fruit) { 
        fruits.add(fruit);
        return fruits;
    }

    @DELETE
    public Set<Fruit> delete(Fruit fruit) { // no JSR validations
        fruits.remove(fruit);
        return fruits;
    }
}

This is the generated OpenAPI spec
