- * An empty class in an empty package.
- * Used as a proxy for unprivileged code, since making access checks
- * against it will only succeed against public methods in public types.
- * <p>
- * This class also stands (internally to sun.dyn) for the type of a
- * value that cannot be produced, because the expression of this type
- * always returns abnormally.  (Cf. Nothing in the closures proposal.)
