Session replication problems with WF15 / eleytron / keycloak
I'm unable to get basic session replication working on WF 15.
Pretty standard setup -- 2 nodes running WF 15 with eleytron security, using keycloak for SSO. Keycloak is running on a different server. Jgroups is setup with TCP based replication. I've installed the keycloak 3.4.3 eleytron add-on. The reason I'm using the 3.4.3 keycloak add-on is because that is the KC server version that we're using, and I'm not in a position to upgrade the KC server to a newer version.
Everything works fine with a non distributable app. I can see jgroups startup just fine and the 2 boxes talking to each other. I can log in with keycloak sso, etc. As soon as I add "<distributable/>" to the web.xml things crap out with the following exception:

Any thoughts on how to fix this issue?
