Hi, Minecraft v1.17 and up will require Java 16 to run successfully, whereas before 1.17, the required Java version was 11+. See: [https://www.minecraft.net/ru-ru/article/minecraft-snapshot-21w19a](https://www.minecraft.net/ru-ru/article/minecraft-snapshot-21w19a) for release notes regarding snapshot 21w19a, which was a snapshot for Minecraft 1.17. @AlexProgrammerDE responded in another thread with a solution: [Error with .jar file - #23 by AlexProgrammerDE](https://forums.balena.io/t/error-with-jar-file/331364/23). In summary, if you are part of an open fleet ([balenaHub: an easier way to find and publish apps and projects for edge devices](https://hub.balena.io/gh_alexprogrammerde/balena-minecraft-server)), your Minecraft server should have been updated automatically to use Java 16, otherwise you can redeploy following the instructions in Alex’s GitHub repo: [GitHub - AlexProgrammerDE/balena-minecraft-server: Build a Minecraft Server using a Raspberry Pi 4! Supports common Servers, SCP, RCON and Wifi Connect.](https://github.com/AlexProgrammerDE/balena-minecraft-server#manually-deploy-this-application-airplane) Let us know if that works for you!
