(1.9) Player Heads

I am trying to set the helmet to a player head by username. Here is the code.

Code (Text):

        case SKULL_ITEM:
            ItemStack mSkull = new ItemStack(Material.SKULL_ITEM, 1, (short)3);
            SkullMeta msMeta = (SkullMeta)mSkull.getItemMeta();
            msMeta.setDisplayName(ChatColor.GREEN + "" + ChatColor.BOLD + "MaxNatural' Head");
            msMeta.setOwner("MaxNatural");
            List<String> msLore = new ArrayList<String>();
            msLore.add(ChatColor.GRAY + "" + ChatColor.ITALIC + "wat");
            msMeta.setLore(msLore);
            mSkull.setItemMeta(msMeta);
         
            player.getInventory().setHelmet(mSkull);
            player.closeInventory();
            }

The player skin does now show for some reason :/
