When debugged I see that
io.undertow.security.impl.AbstractSecurityContext
has 3 notification receivers and first notification receiver fails.
3 receivers are
org.wildfly.extension.undertow.security.LogoutNotificationReceiver io.undertow.servlet.handlers.security.CachedAuthenticatedSessionHandler$SecurityNotificationReceiver org.keycloak.adapters.undertow.AbstractUndertowKeycloakAuthMech
