That’s very good to hear. Either should be totally fine. The only downside I know is that forge and/or some mods don’t work with versions other than Java 8.

Thanks for confirming. Yes, you may want to scale back that value if running multiple minecraft containers. I believe with Java 9 and newer it becomes more container-aware to do a little better at guessing CPU and memory constraints within the container. There’s image tags adopt11 and adopt13 if you want to experiment with that.
