To Reproduce

1. Run rtx ls-remote java command.

the metadata I use comes from this: https://github.com/joschi/java-metadata. I'm not sure why this version is not in there.

Usually you wont find ARM builds for JDK 8 versions for some of the vendors. Only a few vendors created ARM builds for older Java versions. Also installing an x64 version on ARM is currently not supported as available versions are filtered by architecture.

As you can see on https://adoptium.net/temurin/archive/?version=8 there is no ARM build for macOS listed, only x64.

A possible workaround could be to download and extract the binary archive directly to ~/.local/share/mise/installs/java/adoptopenjdk-8u392-b08. You might need to move the content of Content/Home to the top directory and create a symlink from Content/Home to the top directory to make it work. Also note that running x64 Java will use the Rosetta emulation and will have a certain performance impact.
