Solved Item Giving

I have a method to give the required items to a player.

Code:

    public void giveItems(Player p) {
        p.getInventory().setItem(0, new ItemStack(Material.IRON_SWORD));
        p.getInventory().setItem(1, new ItemStack(Material.FLINT_AND_STEEL, 1, (byte) 63));
        p.getInventory().setItem(2, new ItemStack(Material.FISHING_ROD));
        p.getInventory().setItem(3, new ItemStack(Material.BOW));
        p.getInventory().setItem(4, new ItemStack(Material.GOLDEN_APPLE));
        p.getInventory().setItem(8, new ItemStack(Material.ARROW, 16));
        p.getInventory().setHelmet(new ItemStack(Material.IRON_HELMET));
        p.getInventory().setChestplate(new ItemStack(Material.IRON_CHESTPLATE));
        p.getInventory().setLeggings(new ItemStack(Material.IRON_LEGGINGS));
        p.getInventory().setBoots(new ItemStack(Material.IRON_BOOTS));
        p.updateInventory();
        p.getInventory().setHeldItemSlot(0);
    }

I do this:

Code:

        giveItems(p2);
        giveItems(p1);

to give the items to 2 players. But it only gives it to the first player. No error, nothing.
The second player (p2) only get's the armor, the inventory stays the same.

[SOLVED] I added a 1 tick delay, and it seemed to work.
