/**
 * <code>LocateRegistry</code> is used to obtain a reference to a bootstrap
 * remote object registry on a particular host (including the local host), or
 * to create a remote object registry that accepts calls on a specific port.
 *
 * <p> Note that a <code>getRegistry</code> call does not actually make a
 * connection to the remote host.  It simply creates a local reference to
 * the remote registry and will succeed even if no registry is running on
 * the remote host.  Therefore, a subsequent method invocation to a remote
 * registry returned as a result of this method may fail.
