[keycloak-user] Persistent sessions

Hello! I saw these questions in the mailing list 2017 and earlier but would like to double check. We'd like to enable persistent session feature of WildFly in Keycloak (in non-HA environment) By doing this in standalone.xml <persistent-sessions path="sessionsStorage"/> It looks like the feature is not working correctly with keycloak: after keycloak reboot the sessions look lossed. Is it a misconfiguration at my side or a totally not supported feature by keycloak? Thanks in advance for explanation
