Pull request overview
This PR updates Keycloak’s FreeMarker configuration initialization to use a versioned Configuration constructor, ensuring FreeMarker runs with defaults aligned to the bundled engine version rather than legacy 2.3.0 “incompatible improvements” behavior.
Changes:
- Replaced deprecated
new Configuration()withnew Configuration(Configuration.VERSION_2_3_32)inDefaultFreeMarkerProvider. - Ensures FreeMarker defaults match the project’s bundled FreeMarker version (
<freemarker.version>2.3.32</freemarker.version>in the rootpom.xml), aligning with security/correctness improvements gated by version flags.
