/// Regression tests to ensure that member metadata is not considered by the
/// deferred loading algorithm, unless mirrors are available.
///
/// This test was failing in the past because the deferred-loading algorithm was
/// adding entities to the K-element-map after we had closed the world and we
/// had created the J-element-map.  Later, when we convert the K annotation to
/// its J conterpart, we couldn't find it in the conversion maps because it was
/// added too late.
///
/// If we add support for mirrors in the future, we just need to ensure that
/// such K annotations are discovered during resolution, before the deferred
/// loading phase.
