Strange problem with scoreboards

Hey guys!
I've coded a little scoreboard but I have a quite strange problem when I activate two objectives: I'm not able to join the server (Internal exception: java.io.IOException: Received string length longer than maximum allowed (18 > 16)). The "best" is that this just happens when there is more tan one objectives in de scoreboard; here is my code:

Code:java

package es.programahermes.Utilidades;
 
import org.bukkit.Bukkit;
import org.bukkit.ChatColor;
import org.bukkit.entity.Player;
import org.bukkit.scoreboard.DisplaySlot;
import org.bukkit.scoreboard.Objective;
import org.bukkit.scoreboard.Score;
import org.bukkit.scoreboard.ScoreboardManager;
 
import es.programahermes.MySQL;
 
public class Scoreboard {
 
    static ScoreboardManager manager = Bukkit.getScoreboardManager();
 
public static void showScore(Player player){
 
        int sed = (int) MySQL.getSed(player);
        int residual = (int) MySQL.getResidual(player);
        ScoreboardManager manager = Bukkit.getScoreboardManager();
        org.bukkit.scoreboard.Scoreboard board = manager.getNewScoreboard();
        Objective obj = board.registerNewObjective("test", "dummy");
        obj.setDisplaySlot(DisplaySlot.SIDEBAR);
        obj.setDisplayName(ChatColor.BOLD+ "Soporte Vital");
        Score residuos = null;
        Score hidratacion = null;
 
 
        if(MySQL.getSed(player)>70){
            hidratacion = obj.getScore(Bukkit.getOfflinePlayer("Hidratación: "+ChatColor.GREEN+sed+"%"));
        }else{
            if(MySQL.getSed(player)<30){
                hidratacion = obj.getScore(Bukkit.getOfflinePlayer("Hidratación: "+ChatColor.GOLD+sed+"%"));
            }else{
                hidratacion = obj.getScore(Bukkit.getOfflinePlayer("Hidratación: "+ChatColor.RED+sed+"%"));
 
            }
        }
 
 
        //residuos
        if(MySQL.getResidual(player)<50){
            residuos = obj.getScore(Bukkit.getOfflinePlayer("Residuos: "+ChatColor.GREEN+residual+"%"));
        }else{
            if(MySQL.getResidual(player)>70){
                residuos = obj.getScore(Bukkit.getOfflinePlayer("Residuos: "+ChatColor.GOLD+residual+"%"));
            }else{
                residuos = obj.getScore(Bukkit.getOfflinePlayer("Residuos: "+ChatColor.RED+residual+"%"));
 
            }
        }
 
        residuos.setScore(0);
        hidratacion.setScore(0);
 
        player.setScoreboard(board);
    }
 
}

By the way i would like to know if is possible not displaying any score or setting it null.

Thanks in advance!

Any idea?

Probably because you have a String longer than 16 in your Scoreboard Objective/Displayname? ChatColors count as characters I believe, so you must shorten the lengths...
