/**
 * {@link BeanProperty} implementation used for passing annotations
 * from JAX-RS endpoint into Jackson. This tries to imitate behavior
 * one would get if actual resource method was used as POJO property;
 * ideally this would be how implementation works but due JAX-RS API
 * limitations, we are only given annotations associated, and that
 * has to do.
