Well, on further inspection, I think it's better not to add
command-line there. They got the information that helped solve the problem by running a command but the problem itself wasn't specific to it and their goal may not have been to run the Java virtual machine that way. The obvious dupe doesn't have
command-line and shouldn't. I wouldn't remove the tag if it were present but I don't want to add it, unless there's a non-obvious reason to that I've been missing. I'll VTC.
