When shutting down, JDBC_PING tries to use a closed connection -------------------------------------------------------------- Key: WFLY-12948 URL: https://issues.redhat.com/browse/WFLY-12948 Project: WildFly Issue Type: Bug Components: Clustering Reporter: Sebastian Laskawiec Assignee: Radoslav Husar Priority: Minor One of the Keycloak demos use {{JDBC_PING}} as discovery protocol (see [here|https://github.com/keycloak/keycloak-containers/blob/master/docker-c...]). One of our users noticed (and I confirmed it) that when shutting Keycloak down, {{JDBC_PING}} tries to use a closed Connection Factory: {code} keycloak_2 | 09:14:34,807 ERROR
