Помогите Простая ошибка в плагине

Всем привет, пишу плагин на сообщения в чат при нажатии на стекло в gui.
Вот код

Code:

    @Override
    public boolean onCommand(CommandSender sender, Command cmd, String commandLabel, String[] args){
    
     Player p = (Player) sender;
     Inventory i = holders.get(p);
     if(i == null)
     {
        
         i = Bukkit.createInventory(null, 3 * 9, ChatColor.BLUE + "Сообщение в чат");
         holders.put(p, i);
        
        
     }
         if(cmd.getName().equalsIgnoreCase("amsg")){ //
            // String s = plugin.getConfig().getString("amessage.one");
             //s = s.replace("&", "\u00a7");
             //Bukkit.broadcastMessage(s);
         ItemStack item = new ItemStack(Material.STAINED_GLASS_PANE);
         SkullMeta meta = (SkullMeta) item.getItemMeta();
         meta.setDisplayName(ChatColor.GREEN + sender.getName() + " пришел к вам в гости");
         meta.setLore(Lists.newArrayList(ChatColor.GREEN + sender.getName() + " пришел к вам в гости"));
         item.setItemMeta(meta);
        
         i.setItem(4, item);
         p.openInventory(i);
        
     }   
    return true;
    
    
 }
    @EventHandler
    public void onClose(InventoryCloseEvent e)
    {
        
      holders.remove(e.getPlayer());   
        
    }
    
    
    
    
    @EventHandler
    public void handle(InventoryClickEvent e)
    {
        
      Inventory i = holders.get(e.getWhoClicked());
      if(i == null) return;
      
      e.setCancelled(true);
      if(i.equals(e.getClickedInventory()) && e.getSlot() == 4)
      {
          ItemStack item = i.getItem(4);
          ItemMeta meta = item.getItemMeta();
          i.setItem(4, item);
          Bukkit.broadcastMessage(ChatColor.GREEN + getName() + " пришел к вам в гости");
          
      }
        
    }

И выдает такую ошибку:

Code:
