Spielernamen durch UUID bekommen

[HeadiPlays]

Heyho,

ich hole mir die UUIDS von allen spielen aus einer MySQL datenbank, nun möchte ich die UUIDs wieder in Namen umwandeln.. das mache ich mit folgendem code.

@SuppressWarnings("deprecation")
    public OfflinePlayer getRankedPlayer(int rank) throws SQLException {
        sql.openConnection();
        Statement st = sql.getConnection().createStatement();
        OfflinePlayer p = null;
        ResultSet rs = st
                .executeQuery("SELECT * FROM `Players` ORDER BY `Coins` DESC");
        if (rs.next()) {
            p = Bukkit.getOfflinePlayer(rs.getString("player"));
        }
        return p;
    }
​

Doch mir wird immer entweder die UUID auf das Schild geklatscht, oder es kommt folgender fehler in der Konsole:
