Solved Scoreboards... Mindblown.

Alright guys, I've used scoreboards before but I've just run into an error and i have no clue why.
My code:

Code:

public static HashMap<Player, NZScoreboard> boards = new HashMap<Player, NZScoreboard>();
 
Player p;
Scoreboard board;
Objective SB;
//Objective bnty;
 
public NZScoreboard(Player p)
{
this.board = Bukkit.getScoreboardManager().getNewScoreboard();
this.p = p;
boards.put(this.p, this);
this.SB = this.board.registerNewObjective("sidebar", "dummy");
//this.bnty = this.board.registerNewObjective("bnty", "dummy");
this.SB.setDisplaySlot(DisplaySlot.SIDEBAR);
//this.bnty.setDisplaySlot(DisplaySlot.BELOW_NAME);
this.SB.setDisplayName(ChatColor.AQUA + "" + ChatColor.BOLD + "NoZen Prison");
//this.bnty.setDisplayName(ChatColor.RED + "" + ChatColor.BOLD + "Bounty");
}
 
public void destroyAndSend()
{
board = Bukkit.getScoreboardManager().getNewScoreboard();
display();
}
 
public Integer getBounty()
{
return new Bounty(p).currentBounty;
}
 
public Integer getDeaths()
{
return NZPrison.plugin.getConfig().getInt(p.getUniqueId() + ".deaths");
}
 
public Integer getOnline()
{
return Bukkit.getOnlinePlayers().length;
}
 
public Integer getKills()
{
return NZPrison.plugin.getConfig().getInt(p.getUniqueId() + ".kills");
}
 
public void setDeaths(int amount)
{
NZPrison.plugin.getConfig().set(p.getUniqueId() + ".deaths", amount);
}
 
public void setKills(int amount)
{
NZPrison.plugin.getConfig().set(p.getUniqueId() + ".kills", amount);
}
 
public void display()
{
Bukkit.broadcastMessage("online: " + getOnline());
Bukkit.broadcastMessage("bounty: " + getBounty());
Bukkit.broadcastMessage("deaths: " + getDeaths());
Bukkit.broadcastMessage("kills: " + getKills());
 
Score online = SB.getScore(op(ChatColor.GREEN + "" + ChatColor.BOLD + "Online"));
online.setScore(15);
Score onlinescore = SB.getScore(op(getOnline() + ""));
onlinescore.setScore(14);
 
Score bounty = SB.getScore(op(ChatColor.RED + "" + ChatColor.BOLD + "Bounty"));
bounty.setScore(13);
Score bountyscore = SB.getScore(op("$" + getBounty()));
bountyscore.setScore(12);
 
Score kills = SB.getScore(op(ChatColor.BLUE + "" + ChatColor.BOLD + "Kills"));
kills.setScore(11);
Score killsscore = SB.getScore(op(ChatColor.WHITE + "" + getKills()));
killsscore.setScore(10);
 
Score deaths = SB.getScore(op(ChatColor.DARK_AQUA + "" + ChatColor.BOLD + "Deaths"));
deaths.setScore(9);
Score deathsscore = SB.getScore(op(ChatColor.WHITE + "" + ChatColor.WHITE + "" + getDeaths()));
deathsscore.setScore(8);
 
Score website = SB.getScore(op(ChatColor.YELLOW + "" + ChatColor.BOLD + "Website"));
website.setScore(7);
Score websitescore = SB.getScore(op("NoZenPvP.org"));
websitescore.setScore(6);
Bukkit.broadcastMessage("Board: " + this.board);
p.setScoreboard(this.board);
}
 
@SuppressWarnings("deprecation")
public static OfflinePlayer op(String name)
{
return Bukkit.getOfflinePlayer(name);
 
}

The code below is used when a player joins.

Code:

if(!(NZScoreboard.boards.containsKey(e.getPlayer().getName())))
{
new NZScoreboard(e.getPlayer()).display();
}
else
{
NZScoreboard.boards.get(e.getPlayer()).display();
 
}

Whenever I join, I get kicked and I don't know why. The "error":

Code:

[19:04:58 INFO]: ztowne13 lost connection: Internal Exception: net.minecraft.util.io.netty.handler.codec.EncoderException: java.lang.NullPointerException
 
[19:04:58 INFO]: ztowne13 left the game.

I have no idea why it doesn't work.
I've tested, all the values in the scoreboard are not null and I'm just completely mindblown.. And help would be fantastic.

 

Is there a stacktrace of the error in the server console?

 

No, none at all. Otherwise i would figure it out . I don't use any try-catch statements and that's why I'm confused.

 

Make sure no labels for scoreboards are longer than 16 chars. (a colour code is worth 2)

 

They aren't :/ that's why I'm confused.

So I just found out that it isn't working because when I get an offlineplayer that doesn't exist it returns a null value... any answers to how I can do this?

Figured it out guys, thanks.
