/**
 * The UnicastRemoteObject class defines a non-replicated remote
 * object whose references are valid only while the server process is
 * alive.  The UnicastRemoteObject class provides support for
 * point-to-point active object references (invocations, parameters,
 * and results) using TCP streams.  <p>
 *
 * Objects that require remote behavior should extend RemoteObject,
 * typically via UnicastRemoteObject. If UnicastRemoteObject is not
 * extended, the implementation class must then assume the
 * responsibility for the correct semantics of the hashCode, equals,
 * and toString methods inherited from the Object class, so that they
 * behave appropriately for remote objects.
