Wybuchanie wody poprzez TNT

Mam oto taki kod: 

	@Override
	public void onEnable(){
		Bukkit.getServer().getPluginManager().registerEvents(this , this);
	}
	
	@EventHandler
	public void onExplode(EntityExplodeEvent e){
		Settings ss = Settings.getInstance();
		Region region = RegionUtils.getAt(e.getLocation());
		if (region == null){
			return;
		}
		Guild g = region.getGuild();
		if (g == null || g.getName() == null){
			return;
		}
		if (g != null) {
			List<Location> s = sphere(e.getLocation(), 5, 5, false, true, 0);
			Map ExplodeMaterials = ss.explodeMaterials;
			for (final Location loc : s) {
				Material mat = loc.getBlock().getType();
				if (ExplodeMaterials.containsKey(mat)) {
					if(mat.equals(Material.WATER)){
						loc.getBlock().setType(Material.AIR);
					}
					else{ loc.getBlock().breakNaturally();
					}
				}
				if (mat.equals(Material.JUKEBOX)) {
					Bukkit.getScheduler().runTaskLater(new Main(), new Runnable(){
						public void run(){
							loc.getBlock().setType(Material.JUKEBOX);
						}
					}, 1L);
				}
			}
			g.setBuild(System.currentTimeMillis() + Settings.getInstance().regionExplode * 1000L);
		    for (User user : g.getMembers()){
		      Player player = Bukkit.getPlayer(user.getName());
		      if (player != null) {
		        player.sendMessage(Messages.getInstance().getMessage("regionExplode")
		          .replace("{TIME}", Integer.toString(Settings.getInstance().regionExplode)));
		      }
		    }
		}
	}
	
	public static List<Location> sphere(Location loc, int radius, int height, boolean hollow, boolean sphere, int plusY){
		List circleblocks = new ArrayList();
		int cx = loc.getBlockX();
		int cy = loc.getBlockY();
		int cz = loc.getBlockZ();
		for (int x = cx - radius; x <= cx + radius; x++) {
			for (int z = cz - radius; z <= cz + radius; z++) {
				for (int y = sphere ? cy - radius : cy; y < (sphere ? cy + radius : cy + height); y++) {
					double dist = (cx - x) * (cx - x) + (cz - z) * (cz - z) + (sphere ? (cy - y) * (cy - y) : 0);
					if ((dist < radius * radius) && ((!hollow) || (dist >= (radius - 1) * (radius - 1)))) {
						Location l = new Location(loc.getWorld(), x, y + plusY, z);
						circleblocks.add(l);
					}
				}
			}
		}
		return circleblocks;
		}

ale oczywiście nie działa tylko to co chcę

Material mat = loc.getBlock().getType();
				if (ExplodeMaterials.containsKey(mat)) {
					if(mat.equals(Material.WATER)){
						loc.getBlock().setType(Material.AIR);
					}
					else{ loc.getBlock().breakNaturally();
					}
				}
				if (mat.equals(Material.JUKEBOX)) {
					Bukkit.getScheduler().runTaskLater(new Main(), new Runnable(){
						public void run(){
							loc.getBlock().setType(Material.JUKEBOX);
						}
					}, 1L);
				}

Pomoże ktoś to naprawić?
