    A code, a error log, and possibly your plugin yml would be helpful, the plugin yml is really optional if you don't want to.

    You are trying to cast non leather items as leather;

    Try using these itemstacks I have provided for you:
    Code:java
    1.  ItemStack hat2 = new ItemStack(Material.DIAMOND_HELMET);
    2. ItemMeta meta2 = hat2.getItemMeta();
    3. meta2.setDisplayName(ChatColor.AQUA + "Diamond Helmet");
    4. hat2.setItemMeta(meta2);
    5. this.inv.setItem(2, hat2);

    BIG AL 117 I don't know very much about ItemStacks and stuff so i could be totally off, but you're casting a Diamond helmet meta into leather armor meta. That may be a problem?

    Funergy

    You are adding the items when he has not the permission and the inventory isn't made.
    and that will give an error.

    Funergy well if he is OP wouldn't it not matter? right?

    @clmcd42 I changed it to this:
    1. ItemMeta meta2 = hat2.getItemMeta();

    You cannot change the color of non-leather items. Make sure to check if the ItemMeta is an instance of LeatherItemMeta.

    Code:
    ItemMeta meta = item.getItemMeta();
if (meta instanceof LeatherItemMeta) {
    ((LeatherItemMeta) meta).setColor(Color.AQUA);
}
