cljbridge fails to create Java VM

Commencez par reproduire cljbridge.init_jvm(start_repl=True) avec les versions de macOS et de Java signalées, puis examinez clojurebridge.cljbridge.init_jvm et son appel à javabridge.start_vm. Suivez les arguments de la JVM jusqu’à identifier l’option vide qui provoque « Unrecognized option ». C’est terminé lorsque la configuration Java 17 ou 21 signalée démarre la VM avec succès sans l’erreur.

This:
cljbridge.init_jvm(start_repl=True)

results in:
RuntimeError: Failed to create Java VM. Return code = -1

My context

• MacOS 15.7.2, Python 3.9.6
• tested with Java temurin@17 & temurin@21 (via brew install)
