<div>I've been using Docker with the HA configuration as described here: <a href="http://blog.keycloak.org/2015/04/running-keycloak-cluster-with-docker.html" target="_blank">http://blog.keycloak.org/2015/04/running-keycloak-cluster-with-docker.html</a></div>

</div>
<div>I ran into the same problem as David Willson describes in the comments, namely a NullPointerException at org.keycloak.models.sessions.infinispan.initializer.OfflineUserSessionLoader.init(OfflineUserSessionLoader.java:25). Looking at the code, it seems
as though a UserSessionPersister was coming back null.</div>
<div><br>
</div>
<div>I added to keycloak-server.json the following:</div>
<div>
<div><br>
</div>
<div> "userSessionPersister": {</div>
<div> "provider" : "jpa"</div>
<div> },</div>
</div>
<div><br>
</div>
<div>and now everything starts ok. Is this the appropriate fix for a clustered configuration?</div>
</div>
