Versions 1.17 and 1.17.1 used java 16, as shown in the manifest:

https://piston-meta.mojang.com/v1/packages/0d9ace8a2ecfd1f4c782786f4b985a499240ff12/1.17.json

"javaVersion": {
  "component": "java-runtime-alpha",
  "majorVersion": 16
},

Java 16 though, isn't LTS, Java 17 is an LTS release, Java 16 stopped receiving support a long time ago

Hmmm that is fair. But then the question is, do we want to be accurate to what mc uses, or follow LTS releases?

If Minecraft still uses it when selecting that version, it would be best to use that since Fabric should be as neutral as possible imo.

This is something that was discussed previously, there was no reason to recommend Java 16 over 17. You can build mods using 17 that still run just fine on 16.

Ah, I didn't see the previous discussion about this, sorry for that.

You can build mods using 17 that still run just fine on 16.

They have different class file versions though. Wouldn't you need to configure the build system with the proper java version to get it to run?

If we don't want to link to an older JDK, it might make sense to have a separate table for the actual java versions.
