 * Override the actions of the final method "readObject()"

 * Read an object from the ObjectInputStream.
 * The class of the object, the signature of the class, and the values
 * of the non-transient and non-static fields of the class and all
 * of its supertypes are read.  Default deserializing for a class can be
 * overriden using the writeObject and readObject methods.
 * Objects referenced by this object are read transitively so
 * that a complete equivalent graph of objects is reconstructed by readObject. <p>
 *
 * The root object is completly restored when all of its fields
 * and the objects it references are completely restored.  At this
 * point the object validation callbacks are executed in order
 * based on their registered priorities. The callbacks are
 * registered by objects (in the readObject special methods)
 * as they are individually restored.
 *
 * Exceptions are thrown for problems with the InputStream and for classes
 * that should not be deserialized.  All exceptions are fatal to the
 * InputStream and leave it in an indeterminate state; it is up to the caller
 * to ignore or recover the stream state.
 * @exception java.lang.ClassNotFoundException Class of a serialized object
 *      cannot be found.
 * @exception InvalidClassException Something is wrong with a class used by
 *     serialization.
 * @exception StreamCorruptedException Control information in the
