Keeping Inventorys Open after it is closed

Hey guys,

Usually, when I have an issue I go to these forums. But I couldn't find one for this.

I'm trying to keep an inventory open (so when the player tries to close it opens again). But, I read from the JavaDoc that you can't open an inventory inside an InventoryCloseEvent, so what people suggested is to schedule a task for like a couple of ticks later... I tried that but it still gives me an error pointing to the line in which the task is scheduled (look below for full console error and code).

If you can tell me what I'm doing wrong I would appreciate it because I can't find this anywhere.

Thanks,
MrPeterss

Code:

public void closeInventory(InventoryCloseEvent e) {
            Inventory i = e.getInventory();
                Bukkit.getServer().getScheduler().scheduleSyncDelayedTask((Plugin) this, new Runnable() {
  
                    @Override
                    public void run() {
                       Player p=(Player) e.getPlayer();
                       p.openInventory(i);
  
                    }
                }, 20);
            }

Code:

Oh yeah I’m kinda dumb. I’ll reroute that to the main class
