无法启动游戏服务器

我尝试按照这里的说明来运行游戏...

https://www.minecraft.net/en-us/download/server

但出现此错误：

# java -Xmx1024M -Xms1024M -jar server.jar  nogui
Error: LinkageError occurred while loading main class net.minecraft.server.Main
        java.lang.UnsupportedClassVersionError: net/minecraft/server/Main has been compiled by a more recent version of the Java Runtime (class file version 60.0), this version of the Java Runtime only recognizes class file versions up to 55.0

我使用以下方式安装 JDK：

apt install openjdk-11-jdk-headless

我正在使用 ARM Ubuntu EC2 实例。

更新：

成功安装 Java。但这次出现了不同的错误 :)
