/**
 * The {@code @Journal} marks a service as needing journaling by the Baratine system.
 * 
 * During startup, journalled calls will be replayed after the state is loaded
 * and before the service is active.
 * 
 * Thus, between the call of the {@code @OnLoad} and
 * the {@code @OnActive} the service is in replay mode and
 * should for example not (perhaps) send messages to foreign service actors.
