Chat Cooldown Help

I am getting a series of Console errors when ever i send a message in Chat.
Basically i am trying to create a Chat cooldown Timer to avoid potential spam within Chat.

Code:java

public class MGChatCooldown implements Listener {
 
 
public MGV2Main plugin;
 
public MGChatCooldown(MGV2Main plugin) {
this.plugin = plugin;
}
 
 
 
public MGChatCooldown() {
}
 
 
 
public static List<String> cooldown = new ArrayList<String>();
 
int cd = 5;
int cdtimer = 5;
 
@EventHandler
public void onCooldownChat(AsyncPlayerChatEvent e) {
final Player p = e.getPlayer();
 
cd = plugin.getServer().getScheduler()
.scheduleSyncRepeatingTask(plugin, new Runnable() {
public void run() {
if (cdtimer != -1) {
if (cdtimer != 0) {
Bukkit.broadcast(ChatColor.RED
+ "Chat Cooldown Debug.. processing.",
"Admin.Debug");
cdtimer--;
}
else if (cdtimer == 4) {
cooldown.add(p.getName());
}
 
else if (cdtimer == 0) {
cooldown.remove(p.getName());
Bukkit.getServer().getScheduler()
.cancelTask(cd);
}
}
}
 
}, 20, 100);
}
 
}
 

Here are my console errors.

Code:

You can use my CooldownManager if you want:

Example:

Code:

public class TheCore extends JavaPlugin implements Listener {
    
    private CooldownManager cooldownManager;
    
    @EventHandler
    public void onEnable() { 
        Bukkit.getServer().getPluginManager().registerEvents(this, this);
        cooldownManager = new CooldownManager(5, Time.SECONDS);
    }
    
    @EventHandler
    public void onChat(AsyncPlayerChatEvent e) {
        if(!(cooldownManager.interact(e.getPlayer()))) {
            e.getPlayer().sendMessage("Please wait " + cooldownManager.timeLeft(e.getPlayer(), Time.SECONDS) + " Seconds");
            e.setCancelled(true);
            return;
        }
    }

}

 

Yonas I'm bookmarking that link. If I start making plugins again, that is going to be so ridiculously useful to me. >
