  72  * <p>
  73  * The registry layers and merges the 2 configuration files: user, and application server.
  74  * </p>
  75  * <p>
  76  * Instead of relying on the model defaults, if the registry is empty a default configuration file is loaded and
  77  * applied from a resource. The defaults are not loaded into the registry as the lists (eg repositories) could no longer
  78  * be removed if that was the case.
  79  * </p>
  80  * <p>
  81  * When saving the configuration, it is saved to the location it was read from. If it was read from the defaults, it
  82  * will be saved to the user location.
  83  * However, if the configuration contains information from both sources, an exception is raised as this is currently
  84  * unsupported. The reason for this is that it is not possible to identify where to re-save elements, and can result
  85  * in list configurations (eg repositories) becoming inconsistent.
  86  * </p>
  87  * <p>
  88  * If the configuration is outdated, it will be upgraded when it is loaded. This is done by checking the version flag
  89  * before reading it from the registry.
