     * Returns a Java reference to the servant which should be used for this
     * request. servant_preinvoke() is invoked by a local stub.
     * If a ServantObject object is returned, then its servant field
     * has been set to an object of the expected type (Note: the object may
     * or may not be the actual servant instance). The local stub may cast
     * the servant field to the expected type, and then invoke the operation
     * directly. 
     *
     * @param self The object reference which delegated to this delegate.
     *
     * @param operation a string containing the operation name.
     * The operation name corresponds to the operation name as it would be
     * encoded in a GIOP request.
     *
     * @param expectedType a Class object representing the expected type of the servant.
     * The expected type is the Class object associated with the operations
     * class of the stub's interface (e.g. A stub for an interface Foo,
     * would pass the Class object for the FooOperations interface).
     *
     * @return a ServantObject object.
     * The method may return a null value if it does not wish to support
     * this optimization (e.g. due to security, transactions, etc).
     * The method must return null if the servant is not of the expected type.
