EnderFurnace (Last thing I should do in my plugin)

The ender thing works but the materials doesn´t cook. They changed the methods of TileEntityFurnace from previous versions.

Code (Text):

public class EnderFurnaceListener implements Listener {
   
    private HashMap<GameTeam, Location> locations;
    private HashMap<String, VirtualFurnace> furnaces;
   
    public EnderFurnaceListener(Annihilation plugin) {
        locations = new HashMap<GameTeam, Location>();
        furnaces = new HashMap<String, VirtualFurnace>();
        Bukkit.getScheduler().runTaskTimer(plugin, new Runnable() {
            public void run() {
                for (VirtualFurnace f : furnaces.values()) {
                    try {
                        f.d();
                    } catch (Exception e) {
                    }
                }
            }
        }, 0L, 1L);
    }
    public void setFurnaceLocation(GameTeam team, Location loc) {
        locations.put(team, loc);
    }
    @EventHandler
    public void onFurnaceOpen(PlayerInteractEvent e) {
        if (e.getAction() != Action.RIGHT_CLICK_BLOCK) {
            return;
        }
        Block b = e.getClickedBlock();
        if (b.getType() != Material.FURNACE) {
            return;
        }
        Location loc = b.getLocation();
        Player player = e.getPlayer();
        GameTeam team = PlayerMeta.getMeta(player).getTeam();
        if (team == null || !locations.containsKey(team)) {
            return;
        }
        if (locations.get(team).equals(loc)) {
            e.setCancelled(true);
            EntityHuman handle = ((CraftPlayer) player).getHandle();
            handle.openContainer(getFurnace(player));
            player.sendMessage(Annihilation.getInstance().getConfig().getString("prefix").replace("&", "§") + " §7Has entrado en el §3horno privado");
           
        } else if (locations.containsValue(loc)) {
            e.setCancelled(true);
        }
    }
    @EventHandler
    public void onFurnaceBreak(BlockBreakEvent e) {
        if (locations.values().contains(e.getBlock().getLocation())) {
            e.setCancelled(true);
        }
    }
    private VirtualFurnace getFurnace(Player player) {
        if (!furnaces.containsKey(player.getName())) {
            EntityPlayer handle = ((CraftPlayer) player).getHandle();
            furnaces.put(player.getName(), new VirtualFurnace(handle));
        }
        return furnaces.get(player.getName());
    }
    private class VirtualFurnace extends TileEntityFurnace {
        public VirtualFurnace(EntityHuman entity) {
            world = entity.world;
        }
        @Override
        public boolean a(EntityHuman entity) {
            return true;
        }

       
        @Override
        public InventoryHolder getOwner() {
            return new InventoryHolder() {
                public Inventory getInventory() {
                    return new CraftInventoryFurnace(VirtualFurnace.this);
                }
            };
        }
    }
}

I think the mistake is f.d(); because it was changed with the version

 

someone knows how to do it?
