     * 2. After RecordableBootstrap builds a StandardServiceRegistry, the first time the EnversService is

     * 3. The MetadataBuildingProcess completes by calling the AdditionalJaxbMappingProducer which
     * initializes the EnversService and produces some additional mapping documents.
     * 4. After that point the EnversService appears to be fully functional.
     *
     * The following trick uses the aforementioned steps to setup the EnversService and then turns it into
     * a ProvidedService so that it is not necessary to repeat all these complex steps during the reactivation
     * of the destroyed service registry in PreconfiguredServiceRegistryBuilder.
