 *
 * These phases only fire after the class loader had a cache fail.
 * This way, all the initialization logic, subscribing module namespaces etc,
 * will not be executed on an average request.
 *
 * Phase switching events can hit the observer later in the request, even if the
 * respective phase has already started long ago. E.g. the enterBootPhase() will
 * still fire even if the cache miss happens during the "main phase".
 *
 * However, the order of phase events being called on an observer will always be
 * the same. And wakeUp() will always be called before any other phase event,
 * giving the observer the chance to set up the finder object.
