Temporary Flying

Ok for some reason my bukkit runnables aren't working....

Code:java

                @EventHandler
                public void onClickItem1(PlayerInteractEvent event){
                final Player player = event.getPlayer();
                if(event.getAction().equals(Action.RIGHT_CLICK_AIR) || event.getAction().equals(Action.RIGHT_CLICK_BLOCK)) {
                    if(event.hasItem() && event.getPlayer().getItemInHand().getType().equals(Material.RED_ROSE)) {
 
                        if (player.hasPermission("CustomKits.Butterfly")){
                            if (!plugin.FlyCooldown.contains(player.getName())){
                                player.setAllowFlight(true);
                                player.setFlying(true);
                                player.sendMessage(ChatColor.GOLD + "You are now flying!");
                                plugin.FlyCooldown.add(player.getName());
                                Bukkit.getServer().getPluginManager().getPlugin("CustomKits").getServer().getScheduler().scheduleSyncDelayedTask(Bukkit.getServer().getPluginManager().getPlugin("CustomKits"), new Runnable() {
                                    @Override
                                    public void run() {
                                        player.setFlying(false);
                                        player.setAllowFlight(false);
                                }
 
                            },15*20);
                                Bukkit.getServer().getPluginManager().getPlugin("CustomKits").getServer().getScheduler().scheduleSyncDelayedTask(Bukkit.getServer().getPluginManager().getPlugin("CustomKits"), new Runnable() {
 
                                    @Override
                                    public void run() {
                                        plugin.FlyCooldown.remove(player.getName());
                                        player.sendMessage(ChatColor.GOLD + "You may now fly again!");
                                }
 
                            },30*20);       
                              }
                              else player.sendMessage(ChatColor.RED + "You must wait to fly again!");                           
                        }
                    }
                }   
                }
}

Whats wrong with it

 

If you have saved the plugin as an instance, why are you getting the plugin through the getPlugin method in line 13 and 21 then?

Is it just not reacting to anything? Do you get any error messages / stack traces?

 

It activates... It gives me fly and then it doesn't every activate the runnables. So I never stop flying. There are no errors at all.
