+/**
+ * <p>
+ * Registers the interceptor.
+ *
+ * Direct interceptor registration would open a security hole. Hence instead the
+ * interceptors from the ORB.init(..) method, passing the names of the needed
+ * initialized classes via properties.
+ * </p>
+ * <p>
+ * These property names are of the form
+ * </p>
+ * <p><i>org.omg.PortableInterceptor.ORBInitializerClass.&lt;Service&gt;</i></p>
+ * where <i>&lt;Service&gt;</i> is the string name of a class, which implements
+ * {@link ORBInitializer}. During <code>ORB.init(..)</code>, the properties
+ * begining with <i>org.omg.PortableInterceptor.ORBInitializerClass</i> are
+ * collected, the <i>&lt;Service&gt;</i> portion of each property is extracted,
+ * the initialiser is instantiated with the <i>&lt;Service&gt;</i> string as its
+ * class name and then <code>pre_init</code> and <code>post_init</code>
+ * (defined in {@link ORBInitializerOperations}) are called on that initializer.
+ * The runtime exceptions, thrown by these two methods, are ignored.
+ * </p>
+ * <p>
+ * <h3>Example</h3>
+ * A client-side logging service may have the following ORBInitializer
+ * implementation:
+ *
+ * <code><pre>
+ * package gnu.x.logging;
+ *
+ * import org.omg.PortableInterceptor.*;
+ * import org.omg.CORBA.LocalObject;
+ *
+ * public class LoggingService extends LocalObject implements ORBInitializer
+ * {
+ * public void pre_init (ORBInitInfo info)
+ * {
+ * // More than one interceptor can be registered.
+ * ServerRequestInterceptor log_requests = new rLoggingInterceptor();
+ * info.add_server_request_interceptor(log_requests);
+ *
+ * IORInterceptor log_iors = new iLoggingInterceptor();
+ * info.add_ior_interceptor(log_iors);
+ * }
+ *
+ * public void post_init (ORBInitInfo info)
+ * {
+ * // Unused.
+ * }
+ * }
+ * </code></pre>
+ * <p>
+ * Then, one of the used set of properties then must contain the property, named
+ * <i>
+ * org.omg.PortableInterceptor.ORBInitializerClass.gnu.x.Logging.LoggingService
+ * </i>.
+ * The value of the property is ignored and may empty string. The
+ * agreed locations, where this property will be searched for, are:
+ * </p><p>
+ * 1. The properties parameter in the ORB.init(..), if any.<br>
+ * 2. The System properties.<br>
+ * 3. The orb.properties file located in the user.home directory (if any).<br>
+ * 4. The orb.properties file located in the java.home/lib directory (if any).
+ * </p>
+ * <p>
+ * The applet parameters and command line arguments are <i>not</i> scanned
+ * for the possible initializers.
+ * </p>
+ * <p>
+ * Interceptors are registered on a per-ORB basis. The virtual per-object
+ * Interceptors can be simulated by checking the policies on the target from
+ * within the interception points to determine whether they should work. The
+ * virtual per-POA Interceptors can be obtained instantiating each POA such with
+ * a different ORB.
+ * </p>
+ * <p>
+ * The registration code should not call directly any methods on the ORB being
+ * registered.
+ * </p>
+ * <p>
+ * The new interceptors cannot be registered after the ORB.init(..) returns.
+ * </p>
