/** This file creates and registers the logging service interceptor used by object servers. Even though this interceptor is meant to only log server-side interception points, it is both a client and server interceptor. The code illustrates how to avoid infinite recursion in the case where the object being called is colocated in the same ORB in which the interceptors are registered.
