Lock ownership change notifications
-----------------------------------

                 Key: JBCLUSTER-274
                 URL: https://jira.jboss.org/browse/JBCLUSTER-274
             Project: JBoss Clustering
          Issue Type: Feature Request
      Security Level: Public (Everyone can see)
          Components: HA-Server-API
            Reporter: Brian Stansberry
            Assignee: Brian Stansberry


Add an ability to register for a notification when ownership of a particular lock changes.

For example, with HttpSession clustering backed by JBC, we currently get callbacks when the cache changes, allowing us to know a local copy of a session is out of date with respect to the distributed cache. That won't work with DIST as the notification is not reliable. But another node taking ownership of the session will be noticed by the local lock manager, which could invoke a notification on the session manager.
