我通过ssh在使用UNIX屏幕的无头机器上运行minecraft服务器（使用openjdk 11的spiggot）。我可以连接到备用计算机上的Xserver以显示正确的gui。我的bash脚本：

#!/bin/bash
export DISPLAY=$@
while true
do
java -server -Xmx1400M -Xms1100M -XX:+AlwaysPreTouch -XX:+DisableExplicitGC -XX:+UseG1GC -XX:+UnlockExperimentalVMOptions -XX:MaxGCPauseMillis=45 -XX:TargetSurvivorRatio=90 -XX:G1NewSizePercent=50 -XX:G1MaxNewSizePercent=80 -XX:InitiatingHeapOccupancyPercent=10 -XX:G1MixedGCLiveThresholdPercent=50 -XX:+AggressiveOpts -jar spigot-1.16.1.jar
echo restarting in 5 seconds. Ctrl-C to cancel.
sleep 5
done

我是这样运行的：$ ./start.sh 192.168.x.x:y，其中x.x是本地ip的2个数字，y是X11端口。我也可以使用主机名。

这在Xserver运行时可以无缝运行

我的问题是，当Xserver停止时（例如，我关闭笔记本电脑），它给出了错误，而不是无头运行：

OpenJDK Server VM warning: Option AggressiveOpts was deprecated in version 11.0 and will likely be removed in a future release.

Xserver脱机时是否可以使服务器无头运行（即仅通过ssh客户端）？

我希望它是一个bash解决方案，因为我不知道任何Java。 （java）命令的标记会更好！
