I have two interfaces:

public interface Store<T extends Record> {
@GET
@Path("/")
@Produces("application/json")
@BadgerFish
@Wrapped
public abstract List<T> list();
}

public interface Accounts extends Store<Account> {}

System is producing following exception on this method call on Accounts implementation:
