### Describe the bug

Developer experience is broken. This affects:
* Running [`IDELauncher`](https://github.com/keycloak/keycloak/blob/36b01cbea093d38c495c9e0f2ef66feb3a3f9e41/quarkus/server/src/main/java/org/keycloak/quarkus/_private/IDELauncher.java) 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](https://github.com/keycloak/keycloak/blob/36b01cbea093d38c495c9e0f2ef66feb3a3f9e41/quarkus/tests/junit5/src/main/java/org/keycloak/Keycloak.java) in junit5 module or [`KeycloakServer` class](https://github.com/keycloak/keycloak/blob/36b01cbea093d38c495c9e0f2ef66feb3a3f9e41/testsuite/utils/src/main/java/org/keycloak/testsuite/KeycloakServer.java) in utils.
