Another thing is that using joptsimple gives up a bit of control, e.g. the help output shows the parameter for --class-path as `<String>` where the java launcher and other tools will show "path" or "class path". Same thing with `--release` where it shows `<String>` where jar, javac, and other tools will say "release". Not important for now, just comments from trying out the tool. ------------- PR Comment: https://git.openjdk.org/jdk/pull/19774#issuecomment-2181070909
