* The BootstrapServer uses a Properties object specify the initial service
* object references supported; such as Properties object is created containing
* only a "NameService" entry together with the stringified object reference
* for the initial NamingContext. The BootstrapServer's listening port
* is set by first checking the supplied arguments to the name server
* (-ORBInitialPort), and if not set, defaults to the standard port number.
* The BootstrapServer is created supplying the Properties object, using no
* external File object for storage, and the derived initial port number.
