Problem Description

Issue

I want to set up a minecraft 1.21.1 Server, which needs a newer Java version to start, updated Java on the server machine (runnin Linux Debian) via console to 21.0.4, checked the instance configuration after. It doesn’t show Temurin 21 at the Java Version selection.

Reproduction Steps

  • Create Minecraft Java Edition Instance
  • update Java Version to 21.0.4 on Server machine
  • checked New Minecraft Java Edition Instance > Configuration > Minecraft > Java and Memory

Try updating the AMP instance, and if that doesn’t work run the following in the system’s CLI:
docker pull cubecoders/ampbase:java
Then stop/start the instance
