Warum kann meine Spring-Boot-App nicht mit Java 25 kompiliert werden? ⇐ Java

[Anonymous]

Ich versuche, meine Spring-App auf Java 25 zu aktualisieren. Ich erhalte die folgende Ausnahme:

Es gibt ähnliche Probleme online, wie zum Beispiel dieses:
Wie kann ich „nicht unterstützte Klassendatei-Hauptversion 60“ in IntelliJ IDEA beheben?
aber ich habe versucht, mein org.springframework.boot auf 3.4.0 und Gradle auf 9.1.0 zu aktualisieren, die angeblich Java 25 sind kompatibel.
BEARBEITEN: Ich habe versucht, org.ow2.asm:asm auf 9.8 zu aktualisieren (was Java 25-kompatibel sein sollte), aber es funktioniert immer noch nicht.
