Area

Describe the bug

Developer experience is broken. This affects:

• Running IDELauncher from the IDE.
• Running mvn -f server/pom.xml compile quarkus:dev -Dquarkus.args="start-dev".

This is caused by https://github.com/keycloak/keycloak/pull/34309.

Workaround is to use either the Keycloak class in junit5 module or KeycloakServer class in utils.

Version

main,release/26.0
