Empty String argument possible with two subsequent String parameters

[petomka]

Consider the following code (to create a chatroom, in this particular case) in a command:

@Subcommand("create")
public void create(CommandSender sender, @Single String name, @Single @Optional String password) {
	// some action
}

If a user types /room_create__something (please think of _ as a space, a double space was formatted away in this editor) name is an empty string and password will be something (because of the double space between create and something!)
As you cannot call other commands that have a String parameter as the last parameter with an empty string by just adding spaces (e.g. /room_delete__), I doubt that this works as intended - I would expect the second argument to actually be the second argument instead of supplying me with an empty string.
