I guess those examples were not tested in cluster environment. It seerms the issue is, that some stateful EJB is trying to serialize, but EJB has reference on DefaultKeycloakSession, which is not serializable (and shouldn't be as it's not supposed to be serialized and sent over network). I am not 100% sure, but if it's possible to get rid of stateful EJB and use "standalone" JPA, it may help. Also it may help if you mark some fields transient in your EJB or write custom infinispan externalizers. See infinispan/Wildfly docs for more info.

Not sure TBH. I would personally get rid of EJB and use "standalone" entity manager. Something similar to what Keycloak itself is doing for manipulate it's JPA model.
