The native libraries in RMI-IIOP standard extension are required
because the JDK doesnt provide a pure-Java way of doing some things
necessary for IIOP serialization.
For EJB implementations, the EJB server vendor would need to provide
an implementation of RMI (over IIOP or some other protocol) that
allows EJB clients to use javax.rmi.PortableObject.narrow on all
OS'es supported by the vendor.
