code: @Deprecated
    public static <T> T firstNonNull(@Nullable T first, @Nullable T second) {
      return MoreObjects.firstNonNull(first, second);
    }
docs: Returns the first of two given parameters that is not {@code null}, if
  either is, or otherwise throws a {@link NullPointerException}.
  
  <p><b>Note:</b> if {@code first} is represented as an {@link Optional},
  this can be accomplished with
  {@linkplain Optional#or(Object) first.or(second)}.
  That approach also allows for lazy evaluation of the fallback instance,
  using {@linkplain Optional#or(Supplier) first.or(Supplier)}.
  
  @return {@code first} if {@code first} is not {@code null}, or
  {@code second} if {@code first} is {@code null} and {@code second} is
  not {@code null}
  @throws NullPointerException if both {@code first} and {@code second} were
  {@code null}
  @since 3.0
  @deprecated Use {@link MoreObjects#firstNonNull} instead. This method is
  scheduled for removal in June 2016.
