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. But maybe it's just me and there is something simple, which can be done to have it correctly working with stateful EJB on Wildfly...
