I have the following Jupyter kernels installed on my HD:

» jupyter kernelspec list
Available kernels:
  python3                /Users/chl/.local/lib/jupyter/share/jupyter/kernels/python3
  clojupyter             /Users/chl/Library/Jupyter/kernels/clojupyter
  common-lisp            /Users/chl/Library/Jupyter/kernels/common-lisp
  racket                 /Users/chl/Library/Jupyter/kernels/racket
  wolfram                /Users/chl/Library/Jupyter/kernels/wolframlanguage14.1

I renamed clojupyter snapshot to something more convenient to handle when calling jupyter console. I’m using OpenJDK 24.0.1 from Homebrew (which I symlinked in macOS default $JAVA_HOME, using sudo ln -sfn /opt/homebrew/opt/openjdk/libexec/openjdk.jdk /Library/Java/JavaVirtualMachines/openjdk.jdk) and I kept getting this annoying warning:

WARNING: A restricted method in java.lang.System has been called
WARNING: java.lang.System::load has been called by org.sqlite.SQLiteJDBCLoader in an unnamed module (file:/Users/chl/Library/Jupyter/kernels/clojupyter/clojupyter-standalone.jar)
WARNING: Use --enable-native-access=ALL-UNNAMED to avoid a warning for callers in this module
WARNING: Restricted methods will be blocked in a future release unless native access is enabled

To get ride of the warning, simply add --enable-native-access=ALL-UNNAMED in the kernel.json init file.
