Upgrade the bundled JDK version to 25 LTS

Aucun fichier ni test n’est nommé ; commencez par localiser le point d’entrée de configuration ou de build qui sélectionne le JDK inclus et vérifiez comment l’extension le package. Vérifiez que le bundle obtenu utilise JDK 25 LTS et démarre correctement avec UseCompactObjectHeaders.

Is your feature request related to a problem? Please describe.
The currently bundled JDK version is 21, which does not recognize the UseCompactObjectHeaders VM option; upgrading to the latest LTS version (25) resolves this issue.
