 * Creates and returns an immutable collection from this proxy class.

 * <a href="Map.html#immutable">Map</a>, or
 * <a href="Set.html#immutable">Set</a>.
 * This proxy class is the serial form for all immutable collection instances,
 * regardless of implementation type. This is necessary to ensure that the
 * existence of any particular implementation type is kept out of the
 * serialized form.

 * @return a collection created from this proxy object
 * @throws InvalidObjectException if the tag value is illegal or if an exception
 *         is thrown during creation of the collection
 * @throws ObjectStreamException if another serialization error has occurred
