Hi,
I am currently encountering a persistent issue while attempting to establish a Minecraft server. Despite having the latest Java Runtime Environment (JRE) installed on Ubuntu (build 11.0.15.10), an error consistently arises whenever I initiate the server launch.
Code:
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 61.0),
this version of the Java Runtime only recognizes class file versions up to 55.0
To address this, I have executed a complete removal and reinstallation of all JRE versions on my server, ensuring only the most recent version is present. Additionally, I have undertaken an upgrade of the server's operating system from Ubuntu 18 to Ubuntu 20. Despite these efforts, the error remains unresolved.
I am reaching out to the community for any insights or solutions to this problem. Your expertise and suggestions would be greatly valued.
Thank you in advance for your assistance.
