With Keycloak 22 come a bunch of breaking changes, see this blog post here for all the important information!

This release now contains:

• fully based on Java 17 (may be breaking)
• using the new default keycloak-admin-client, which is based on jakarta.* namespace (breaking)
• revised value of the default context path - the server url returned by getAuthServerUrl() now does not end with a / (slash) at the end if you provided no custom context path! (breaking)
• make the method getKeycloakDefaultVersion() public, to be able to get the information from the container during runtime, e.g. in automated tests (not breaking)
