cljbridge fails to create Java VM

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)

Error

At commandline:

cljbridge version: 0.0.8

(.venv) % python3 -m pip install cljbridge
Requirement already satisfied: cljbridge in ./.venv/lib/python3.9/site-packages (0.0.8)

Comece reproduzindo cljbridge.init_jvm(start_repl=True) com as versões de macOS e Java informadas e, em seguida, inspecione clojurebridge.cljbridge.init_jvm e sua chamada a javabridge.start_vm. Rastreie os argumentos da JVM até identificar a opção vazia que causa “Unrecognized option”. Considera-se concluído quando a configuração informada do Java 17 ou 21 inicia a VM com sucesso, sem o erro.
