Get count of certain item in inventory and taking

Don't work.
type = material
am = amount
me = meta-data

Code (Java):

            if (!p.getInventory().contains(new ItemStack(type, am, me))) {
                // If player has no fuel
                p.sendMessage(msg("not-enough-fuel"));
                e.setCancelled(true);
                p.setFlying(false);
                return;
            } else
                p.getInventory().removeItem(new ItemStack(type, am, me));

I also tried this, but it not work too:

Code (Java):

if (!p.getInventory().containsAtLeast(new ItemStack(type, am, me), am))
