java.util.List contains null if query param doesn't specified

[extbe]

Hi!

I'm trying to receive values of a query parameter as java.util.List in my MVC controller

@Path("/")
public class Controller {

  @GET
  public String sayHi(@QueryParam List<String> names) {
    return "Welcome to Jooby!";
  }
}

But if I send a request without specifying the parameter, the names list will contain one element - null
