I followed [spring-security-oauth/oauth-jwt/jwt-auth-server at master · Baeldung/spring-security-oauth (github.com)](https://github.com/Baeldung/spring-security-oauth/tree/master/oauth-jwt/jwt-auth-server) and was able to start Keycloak in SpringBoot app. If I deployed it as a war file in Wildfly 24, it throws the following error

The reason that I need it as a war is client is providing Wildfly and so try to avoid to create another standalone Wildfly instance
