Which Java version to use for Minecraft server?

Minecraft servers run on Java, and each version of Minecraft requires a compatible Java version. Using the wrong Java version may prevent the server from starting or cause plugins, mods to fail during startup.

1.16.5 and below	Java 8
1.17	Java 16
1.18 to 1.20.4	Java 17
