+ * Replaces original class with a simple wrapper to avoid missing reference issue on native-image.
+ *
+ * <p>The original class is only used for testing purposes when a particular property is set, but
+ * native-image follows the reference in {@code LazyStorage} and attempts to load everything it
+ * touches, including some types we are not embedding. This simple replacement fixes this issue.
