Código:

    @EventHandler
    public void itemMergeEvent(ItemMergeEvent event) {

        Item one = event.getEntity();
        Item two = event.getTarget();

        if (one.getCustomName() != null && two.getCustomName() != null) {
            one.setCustomName(String.valueOf(toInt(one.getCustomName()) + toInt(two.getCustomName())));
            two.remove();
        } else if (one.getCustomName() != null && two.getCustomName() == null) {
            one.setCustomName(String.valueOf(toInt(one.getCustomName()) + two.getItemStack().getAmount()));
            two.remove();
        } else if (one.getCustomName() == null && two.getCustomName() != null) {
            two.setCustomName(String.valueOf(toInt(two.getCustomName()) + one.getItemStack().getAmount()));
            one.remove();
        } else {
            one.setCustomName(String.valueOf(one.getItemStack().getAmount() + two.getItemStack().getAmount()));
            one.getItemStack().setAmount(1);
            one.setCustomNameVisible(true);
            two.remove();
        }

        event.setCancelled(true);
    }

    @EventHandler
    public void itemPickUp(EntityPickupItemEvent event) {
        if (event.getEntity() instanceof Player) {

            Inventory inventory = ((Player) event.getEntity()).getInventory();

            Item item = event.getItem();

            if (item.getCustomName() != null) {
                int quantity = NumberUtils.toInt(item.getCustomName());

                if (quantity == 0) return;

                event.setCancelled(true);

                quantity = InventoryUtils.addItemTo(inventory, item.getItemStack(), quantity);

                if (quantity == 0) {
                    item.remove();
                } else {
                    item.setCustomName(String.valueOf(quantity));
                }

            }
        }
    }

    public static int addItemTo(Inventory inventory, ItemStack item, int amount) {

        int stackSize = item.getMaxStackSize();
        int max = (inventory instanceof PlayerInventory) ? 36 : inventory.getSize();

        ItemStack clone = item.clone();

        for (int i = 0; i < max; i++) {
            ItemStack stack = inventory.getItem(i);

            if (stack == null) {
                if (amount >= stackSize) {
                    clone.setAmount(stackSize);
                    inventory.setItem(i, clone);
                    amount -= stackSize;
                    continue;
                }
                clone.setAmount(amount);
                inventory.setItem(i, clone);
                return 0;
            } else if (stack.isSimilar(item)) {
                int stackAmount = stack.getAmount();
                int free = stackSize - stackAmount;
                if (amount > free) {
                    stack.setAmount(stackAmount + free);
                    amount -= free;
                    continue;
                }
                stack.setAmount(stackAmount + amount);
                return 0;
            }
        }

        return amount;
    }

Deixa o like ai :) '-'
