Unable to access Activiti Explorer

[mcpierce]

Activiti v5.17.0
Wildfly v8.1.0

When I deploy the activiti-explorer.war file and then try to go to localhost:8080/activiti-explorer I'm seeing:

08:49:20,853 ERROR [io.undertow.request] (default task-1) Blocking request failed HttpServerExchange{ GET /activiti-explorer/}: org.infinispan.commons.CacheListenerException: ISPN000280: Caught exception [java.lang.NullPointerException] while invoking method [public void org.wildfly.clustering.web.infinispan.session.In
finispanSessionManager.activated(org.infinispan.notifications.cachelistener.event.CacheEntryActivatedEvent)] on listener instance: org.wildfly.clustering.web.infinispan.session.InfinispanSessionManager@48fcdf14

But when I do the exact same steps with Tomcat 8.0.23 I get a running instance of Activiti. Any ideas?

Hmmm… not really.
Seems to be something going on with the session management .. having infinispan in there makes me guess it's about clustered session replication? Any way that can be disabled on your wildfly install?

Hrm, it's a plain Wildfly install, I didn't enable anything in it. If I deploy to Tomcat all works fine, as expected…

No, didn't say that. It's probably a default Wildfly configuration that is enabled by default now.
