Jraps

good question, thats a template i pasted, its still a jar, idk what the dash o does but it used to work, now it says it doesnt, so its removed, and it works, idk why the template said exe, as of rn mine says "java -Xmx3G -Xms3G -jar server.jar" it just used to have the -o true after it

i was just attempting to start a server with the usual " java -Xmx####M -Xms####M -exe Minecraft_Server.exe -o true " format in my bat file, but it seems it didnt understand the -o so i removed it and the true as well and it ran

after removing -o from my bat it works, but what side effects will that have on it?

As you can see bellow i keep getting this weird error, im not sure how to understand what its trying to tell me when it comes to whats the problem any help with this situation would be greatly appreciated
