  /**
   * Knows how to serialize and deserialize the booter configuration.
   * <br>
   * The internal serialization format is through a properties file. The long-term goal of this
   * class is not to expose this implementation information to its clients. This still leaks somewhat,
   * and there are some cases where properties are being accessed as "Properties" instead of
   * more representative domain objects.
