[Feature Request] Toggle Download of Vanilla Minecraft

hi,

i would love to see an toggle like true/false for turning off Downloading latest Vanilla version.

i use mostly Papermc and waterfall for bungeecord and i dont need the vanilla jar.

Like this its waste of space. When i run like 10 servers (game servers) and every server has like 40mb - 50mb wasted space it would use 400mb - 500mb of my harddrive for nothing

Server is not restarted after crash

If the minecraft server process crashes, a manual restart of the container is required to get it back in working order. I would expect that either the minecraft server process is restarted automatically inside the container, or that the entire container goes down (so that it can be restarted by an orchestrator).

Server is not properly shutdown on docker restart/stop

I was doing some testing with a server status bot and it would post a message on when the server has stopped. Stopping the docker container does not cause the server to properly stop and abruptly shuts it down. This could lead to corrupted saves and loss of world data.

Issue with Forge for 1.18.2

I have used forge without issues previous to 1.18.2. Since this version forge has changed the way they package their software so that it is no longer a single .jar

I have got it working by manually editing the docker and replacing the following line in start.sh:

screen -L -Logfile '/config/minecraft/logs/screen.log' -d -S minecraft -m bash -c "cd /config/minecraft && java -Xms${JAVA_INITIAL_HEAP_SIZE} -Xmx${JAVA_MAX_HEAP_SIZE} -XX:ParallelGCThreads=${JAVA_MAX_THREADS} ${java_log4j_mitigation} -jar ${CUSTOM_JAR_PATH} nogui"

With:
screen -L -Logfile '/config/minecraft/logs/screen.log' -d -S minecraft -m bash -c "cd /config/minecraft && /usr/lib/jvm/java-17-openjdk/bin/java @user_jvm_args.txt @libraries/net/minecraftforge/forge/1.18.2-40.2.1/unix_args.txt "$@""

Note that originally it was using java 19 by default and that was causing it to crash, i had manually installed 17 and that is now working with the above.

1. Can you make it so that java 17 is selectable along side 8 , 11 and latest?
2. Is is possible to adjust the start command to be able to take the below line or a variation of command? @user_jvm_args.txt is probably not needed as its a file where you would put all the Xms/Xmx etc args.

@user_jvm_args.txt @libraries/net/minecraftforge/forge/1.18.2-40.2.1/unix_args.txt "$@"

Not allowing additional java flags

I love your containerized Minecraft server by the way you mostly set up things. However, is it possible to add a key for extra Java flags by restructuring the start? sh flags in the start function.

Currently, you have this code on line 124 in start.sh:
screen -L -Logfile '/config/minecraft/logs/screen.log' -d -S minecraft -m bash -c "cd /config/minecraft && java -Xms${JAVA_INITIAL_HEAP_SIZE} -Xmx${JAVA_MAX_HEAP_SIZE} -XX:ParallelGCThreads=${JAVA_MAX_THREADS} ${java_log4j_mitigation} -jar ${CUSTOM_JAR_PATH} nogui"

Again, add another key to the container called {JAVA_EXTRA_PARAMS} and a function to take all the added parameters separated by a comma and replace them with spaces or something.
Example:
JAVA EXTRA PARAMS ---> -XX:+UseG1GC, -XX:+AlwaysPreTouch, etc

screen -L -Logfile '/config/minecraft/logs/screen.log' -d -S minecraft -m bash -c "cd /config/minecraft && java -Xms${JAVA_INITIAL_HEAP_SIZE} -Xmx${JAVA_MAX_HEAP_SIZE} -XX:ParallelGCThreads=${JAVA_MAX_THREADS} {JAVA_EXTRA_PARAMS} ${java_log4j_mitigation} -jar ${CUSTOM_JAR_PATH} nogui"

the reason is that there are more flags that can be added, such as ShenandoahGC or whatever else to fine-tune the server.

Currently, I am using your container as a home for folia because of your backup feature and I am not that smart at building containers.

Let me know what you think.

Allow garbage collection selection, additional startup args

I'm currently trying to get a Minecraft server copied over from my Windows desktop to my Unraid NAS that's running a FeedTheBeast modpack. However, the current Docker config does not allow me to set the necessary startup args that are necessary (or at least recommended).

Specifically, the command line I'm currently using is:

java.exe -server -XX:+UseG1GC -XX:+UnlockExperimentalVMOptions -Xmx6144M -Xms4096M -jar forge-1.12.2-14.23.5.2846-universal.jar nogui

-server, -Xmx, -Xms, -jar, and nogui are all already either configurable or not necessary. However, UseG1GC and UnlockExperimentalVMOptions are not. Additionally, I believe UseG1GC conflicts with the -XX:ParallelGCThreads that is currently getting passed in.

Would it be possible to add the option to set these properly? Or alternatively, adding the option for a CUSTOM_STARTUP_COMMAND variable or similar that, if set, overrides the current startup command?

Netty issues and extreme server lag (Unraid Docker)

Hi team,
I'm getting a constant error about netty and the server is uplayable with lag (can't walk through doors once connected).

See settings I use and error from the console:

There is no screen to be attached matching minecraft.

The game now requires Java 17 instead of Java 16.

The newest pre-release requires a newer version of java. The first PR from 1.18 worked via setting the CUSTOM_JAR_PATH.

JAVA_VERSION does not seem to respect 17 as a setting.

Change server version

Since there's no way to set the server version via an environmental variable I tried copying the jar I wanted and renamed it to minecraft_server.jar. It gets overwritten with the 1.16.5 version though.

Add Java Version 16 to support upcoming releases

I'm running a local papermc server and this warning started to show up lately:

---

• WARNING - YOU ARE RUNNING AN OUTDATED VERSION OF JAVA.
• PAPER WILL STOP BEING COMPATIBLE WITH THIS VERSION OF
• JAVA WHEN MINECRAFT 1.17 IS RELEASED.
• Please update the version of Java you use to run Paper
• to at least Java 16. When Paper for Minecraft 1.17 is
• released support for versions of Java before 16 will
• be dropped.
• Current Java version: 11.0.10
• Check this forum post for more information:
• https://papermc.io/java16

---

If you would add Java version 16 to list of options, it would be great.

Which would also require changing the available environment variables from

-e JAVA_VERSION=<8|11>

to

-e JAVA_VERSION=<8|11|16>

amongst other things of course.
