SPONGEVANILLA is broken

[vorburger]

Describe the problem

It looks like the SPONGEVANILLA integration some got broken, I'll add the full log below, but TL;DR:

$ docker run -p 25565:25565 -e EULA=TRUE -e TYPE=SPONGEVANILLA --rm --name mc itzg/minecraft-server
(...)

This is blocking me in OASIS-learn-study/minecraft-storeys-maker#267 for https://www.learn.study...

... I'll see if I can fix it myself, and propose a PR if I do. Unless anyone else reading this gets to it before me.

You need to use one of the Java 8 based images for Minecraft versions less than 1.17:

Gotcha, right... podman run -p 25565:25565 -e EULA=TRUE -e TYPE=SPONGEVANILLA --rm --name mc itzg/minecraft-server:java8 works indeed! Perhaps #1095 helps to clarify for future users? PS: Thanks for maintaining this project!
