      Deploy attached test.war to two clustered instances on the same host (so the SSO cookie is shared).

      Access http://<hostname>:<port>/test for both instances.
      Access http://<hostname>:<port>/test?x=1 for one instance (the x=1 triggers a session.invalidate() call)

      Expected Result: no errors
      Actual Result: The exception in the description

    Description

      When ClusteredSingleSignOn is enabled, and a user has an active session in a non-distributable web application, invalidating any session in the same SSO from a different AS instance in the cluster causes the following exception (logged numerous times in various ways):

      ERROR [org.infinispan.interceptors.InvocationContextInterceptor] (OOB-20,null) ISPN000136: Execution error: org.infinispan.CacheException: Caught exception [java.lang.ClassCastException] while invoking method [public void org.jboss.as.clustering.web.sso.infinispan.SSOClusterManager.cacheEntryRemoved(org.infinispan.notifications.cachelistener.event.CacheEntryRemovedEvent)] on listener instance: org.jboss.as.clustering.web.sso.infinispan.SSOClusterManager@28e13c84

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
