I’m trying to set a quarkus configuration, but I can not find any trace of the property actually being used.

I’ve tried with setting`-Dquarkus.datasource.jdbc.max-lifetime=12H` in `JAVA_OPTS` and/or `quarkus.datasource.jdbc.max-lifetime=12H` in `conf/quarkus.properties` but I can’t find any trace of it actually being set in the logs or anything.

How can I verify that the configuration is actually used? Or am I not doing as intended? Followed the documentation [here](https://www.keycloak.org/server/configuration#_unsupported_server_options).

Also created in issue if this should be keycloak server configuration, [here](https://github.com/keycloak/keycloak/issues/12316).

As far as I know, you’re not supposed to change quarkus properties directly, and, from Keycloak 17.0.0 you’re supposed to pass that kind of configuration to your kc.sh/kc.bat script (like --db mysql --hostname …)

BTW, maybe you’re trying to make something else (like modifying the amount of memory quarkus reserves by default)?
