+	 * @deprecated This method's results are unpredictable. The string "Steve" will return the player named "SteveJobs",
+	 * until another player named "Steve" joins the server, at which point it will return that player instead. Use

 	 * Returns an online player whose name begins with or equals the given string (case insensitive).
 	 * The closest match will be returned, or null if there are no online matches.
