Annotations not working on single object but working fine on list<> of objects (on Glassfish4)

[ChristBE]

jackson-annotations-2.2.3.jar =============== WORKING ===================== c:>curl -H "Accept:application/json" http://localhost:8080/emberGF4/rest/customers {"customers":[{"id":1,"first_name":"F1","last_name":"L1","order_ids":[1]},{"id":2,"first_name":"F2","last_name":"L2","order_ids":[]}]}

produced by: @GET @Produces(MediaType.APPLICATION_JSON) public Customers get(@QueryParam("ids[]") List ids) { if (ids != null && !ids.isEmpty()) { return new Customers(manager.findByIds(ids)); } return new Customers(manager.findAll()); }

@JsonRootName("customers")
class Customers extends ArrayList<Customer> {
    private static final long serialVersionUID = 1L;

    public Customers(Collection<? extends Customer> c) {
        addAll(c);
    }
}

=============== NOT WORKING ===================== c:>curl -H "Accept:application/json" http://localhost:8080/emberGF4/rest/customers/2 {"firstName":"F2","id":2,"lastName":"L2","orders":[]}

On single object the @JsonRootName("customer") is missing and @JsonIdentityReference(alwaysAsId = true) @JsonProperty("order_ids")

produced by: @Path("/{id}") @GET @Produces(MediaType.APPLICATION_JSON) public Customer get(@PathParam("id") Long id) { Customer c = manager.find(id); return c; }

Could you re-file at jackson-databind -- annotations package just contains annotations, databind actually uses them. So bugs here would be only for direct additions to annotation types.
