Can't use DB::table expression in my Facade Class - Laravel 4

Question

Can't use DB::table in my class. I get a handleShutdown. Please can some one tell me why. I'm spending hours on this and I might be going mad.

Follow below the code:

app/acl/Acl.php

namespace AccessControl;

class Acl 
{

    public function hasPermission($group_id, $module_name, $permission_type) {

      $result = DB::table('permission')->get();
      return $result;
    }
}

app/acl/AclFacade.php

namespace AccessControl\Facades;

use Illuminate\Support\Facades\Facade;

class Acl extends Facade {

    protected static function getFacadeAccessor() { return 'acl'; }

}

app/acl/AclServiceProvider

namespace AccessControl;

use Illuminate\Support\ServiceProvider;
use Illuminate\Foundation\AliasLoader;


class AclServiceProvider extends ServiceProvider {

    public function register()
    {
        // Register 'acl' instance container to our acl object
        $this->app['acl'] = $this->app->share(function($app)
        {
            return new Acl;
        });

        // Shortcut so developers don't need to add an Alias in app/config/app.php
        $this->app->booting(function()
        {
            $loader = AliasLoader::getInstance();
            $loader->alias('Acl', 'AccessControl\Facades\Acl');
        });
    }
}

app.php

'providers' => array(

'Illuminate\Foundation\Providers\ArtisanServiceProvider', 'Illuminate\Auth\AuthServiceProvider', 'AccessControl\AclServiceProvider',

composer.js

      "psr-0": {
          "App\\": "app/",
          "App\\Acl\\": "app/acl",

[...]
      "classmap": [
          "app/commands",
          "app/acl",
[...]

And i used the command

Composer Dump.

You have to tell PHP it is in the root namespace:

$result = \DB::table('permission')->get();

Or use it in the top of your .php file:

use DB;
