Im trying to make a server for the 1.21 in raspberry pi 4 b and i have this error

[Aimar27]

Im using this code:
docker run -e EULA=TRUE -it -v dataminecraft:/minecraft -p 25565:25565 -p 19132:19132/udp -p 19132:19132 --restart unless-stopped itzg/minecraft-server:java17

And this is the error:
LinkageError occurred while loading main class net.minecraft.bundler.Main
java.lang.UnsupportedClassVersionError: net/minecraft/bundler/Main has been compiled by a more recent version of the Java Runtime (class file version 65.0), this version of the Java Runtime only recognizes class file versions up to 61.0

Can someone help me?

Thank you itzg but the raspberry pi 4 is arm v8
If I try with java 21 I got these mesage

Unable to find image 'itzg/minecraft-server:java21' locally
java21: Pulling from itzg/minecraft-server
docker: no matching manifest for linux/arm/v8 in the manifest list entries.

Im afraid I am constrained by the upstream Java distribution images all of which seem to no longer support arm/v8 😒
