Known issues & safety notes

  • Preview builds are experimental: they can corrupt or irreversibly upgrade worlds, and most plugins and mods do not support them yet. Test on a copy of your world.
  • Log4Shell (CVE-2021-44228): for the vanilla 1.17 server Mojang says to add -Dlog4j2.formatMsgNoLookups=true to the Java start command (Mojang advisory).
  • Known issues: search SpongeVanilla's issue tracker for 1.17-pre1

How to set up SpongeVanilla 1.17 Pre-Release 1

  1. Install Java 16 or newer (e.g. Eclipse Temurin) and check it with java -version.
  2. Download the SpongeVanilla jar into an empty folder.
  3. Start it once with the script below; it creates eula.txt and stops.
  4. Set eula=true in eula.txt to accept the Minecraft EULA, then start again. Players join on port 25565.

Rule of thumb: 2–4 GB for a few friends, 6–10 GB for a public server with plugins. Set -Xms equal to -Xmx and leave 1–1.5 GB for the operating system. How much RAM?
