/*
 * Ensure that the default registry port for java.rmi.Naming URLs
 * is 1099. Test creates a registry on port 1099 and then does a
 * lookup with a Naming URL that uses the default port. Test fails
 * if the lookup yields a NotBoundException. If the registry could
 * not be created, a fallback strategy of using an existing one is
 * tried.
