Problem with something, no stacktrace

So I have a problem in my plugin where it is meant to randomly spawn meteors which are fallingBlocks which have explosion particles around them and once the server detects the block is above something that isn't air, it creates a primed tnt entity at that location, but for some reason it doesn't work; any help?

Code:java

    public void onEnable(){
        getServer().getPluginManager().registerEvents(this, this);
        getLogger().info("Better Explosions Enabled");
        getLogger().severe("Uh oh! The plugin is DEAD!!! (or broken)");
        getConfig().options().copyDefaults(true);
        saveConfig();
        Bukkit.getServer().getPluginManager().registerEvents(this, this);
    }
 
    public void onDisable(){
        getLogger().info("Better Explosions Disabled");
        getLogger().severe("Uh oh! The plugin is DEAD!!! (or broken)");
    }
 
    @EventHandler
    public void onEntityExplode(final EntityExplodeEvent event) {
        for(Block b : event.blockList()){
            /*Generates random location to spray blocks*/
            float x = (float) -2 + (float) (Math.random() * ((2- -2) +1));
            float y = (float) -3 + (float) (Math.random() * ((3- -3) +1));

                FallingBlock fallingBlock = b.getWorld().spawnFallingBlock(

                fallingBlock.setDropItem(false);
                fallingBlock.setVelocity(new Vector(x, y, z));
 
                b.setType(Material.AIR);
        }   
 
        Random rand = new Random();
 
        BukkitScheduler scheduler = Bukkit.getServer().getScheduler();/*Schedules random event*/
        scheduler.scheduleSyncDelayedTask(this, new Runnable() {
            @Override
            public void run() {
                int random = new Random().nextInt(Bukkit.getOnlinePlayers().length);
                Player player = Bukkit.getOnlinePlayers()[random];
                Location location = player.getLocation();
                World world = player.getWorld();
                Location center = location;
                        Random rand = new Random();
                        double angle = rand.nextDouble()*360; //Generate a random angle
                        double x = center.getX() + (rand.nextDouble()*100*Math.cos(Math.toRadians(angle)));
                        double z = center.getZ() + (rand.nextDouble()*100*Math.sin(Math.toRadians(angle)));
                        double y = center.getY() + 700; /*Finds new location*/
                        Location newloc = new Location(world, x, y, z);
                        FallingBlock TNT = location.getWorld().spawnFallingBlock(newloc, Material.TNT, (byte)0); //creates the falling block
                        TNT.setVelocity(new Vector());
                        TNT.setDropItem(false);
                        Location tntloc = TNT.getLocation();
                        ParticleEffect.EXPLODE.display(tntloc, 2, 3, 1, 100, 100);
                        if (TNT.getLocation().subtract(0,1,0).getBlock().getType() != Material.AIR){
                            Entity tnt = tntloc.getWorld().spawnEntity(tntloc, EntityType.PRIMED_TNT);
                            tnt.setTicksLived(7);
                            TNT.remove();
                            player.sendMessage(ChatColor.LIGHT_PURPLE + "Test, this means the plugin works ;D");
                            }
            }
        }, (long) rand.nextInt(567));
 
    }
}
