- * If this feature is supported, there is a single instance of it.
- * It adds persistence to Drools sessions, but it is also intertwined with
- * active/standby state management and IntegrityMonitor. For now, they are
- * all treated as a single feature, but it would be nice to separate them.
- *
- * <p>The bulk of the code here was once in other classes, such as

- * a separate optional feature.
