package sun.invoke.empty;

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.

This class also stands (internally to sun.invoke) 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.)
