In previous versions of of JBoss EAP 6, the SSO valves did not set the context when expiring sessions associated with SSO. This meant that ClusteredSingleSignOn would call `WeldListener.sessionDestroyed(event)` after the session has been destroyed, resulting in a `ContextNotActiveException` upon session invalidation. In this version of the product, the SSO valves now set the context when expiring sessions associated with SSO and the `ContextNotActiveException` is avoided upon session invalidation.
