Expected behavior

Player1 or Console performed command:

/tt 1 2  3   4    5     0

TestPlugin onCommand handler received:

arguments: ["1", "2", "3", "4", "5", "0"]

Observed/Actual behavior

Player1 performed command:

/tt 1 2  3   4    5     0

TestPlugin onCommand handler received:

arguments: ["1", "2", "3", "4", "5", "0"]

Console performed command:

/tt 1 2  3   4    5     0

TestPlugin onCommand handler received:

arguments: ["1", "2", "", "3", "", "", "4", "", "", "", "5", "", "", "", "", "0"]

Steps/models to reproduce

@Override
public boolean onCommand(CommandSender theSender, Command theCommand, String labelString, String[] arguments) {
	if (theCommand.getName().equalsIgnoreCase("tt")) {
		System.out.println("arguments: [\"" + String.join("\", \"", arguments) + "\"]");
		return true;
	}

	return false;
}

Then try to perform tt command with more than 1 space between arguments from game chat and server console and see the difference. This problem can break some plugins which do not expect to see empty strings as the argument value, because you can't send an empty argument from a game chat.
