Do you know anything about servers? He wanted it to restart, not crash, /realoading and /stopping will crash the server. The correct way to stop a server is typing stop.sh in the console and once it has stoped you type start.sh to start it again.
Mineverse runs on PaperSpigot 1.8.8, and so it will. Your server probably doesn't run on that and probably is not a bungee cord. I have great experience with system administration, and on most PaperSpigot servers, it will crash it and most likely damage plugins.
