Issue running Minecraft Server on Clear Linux's OpenJDK docker images

Q&A
1

I’m recently trying to setup my Minecraft server with Clear Linux’s OpenJDK 19.0.2.7.1 docker image. But I have so far ran into an issue when trying to run the server

[23:22:20] [main/ERROR]: Failed to start the minecraft server
joptsimple.UnrecognizedOptionException: m is not a recognized option

I’m running the server with Fabric and on Pterodactyl, and this seems to only happen when I use any of the Clear Linux’s OpenJDK docker images and not other OpenJDK images.
The thing is, I have tried booting up a Clear Linux VM (just ISO with Java on top, not docker image bc I haven’t had success in making a container with that) and run the exact same command with the same Java version, and it seems to be working alright.

Here is the full log of the Minecraft server:

Here is what it should looks like:

This is the install script I wrote:

cd /mnt/server

Here is the Minecraft startup command:
java -Xms128M -Xmx{{SERVER_MEMORY}}M -jar {{SERVER_JARFILE}}

Here is the image I used to run the MC server & script container:
clearlinux/openjdk:19.0.2.7.1

Here is the script I based on to wrote my script which work flawlessly (use openjdk:11-jdk-slim as script container, Package yolks · GitHub to run Minecraft, same MC startup command):

#!/bin/bash

# Server Files: /mnt/server
apt update
apt install -y curl jq unzip dos2unix wget

It’s quite an oddly specific question honestly, I have tried searching but to know avail, so I’d be glad if you are able to help :smile:
