if DiExtraBundle not available, JMSSerializer crash

[asquel]

If you uninstall DiExtraBundle, you get this error :
Compile Error: Symfony\Component\Debug\DebugClassLoader::loadClass(): Failed opening required '/home/asquel/www/pnp2014/vendor/jms/di-extra-bundle/JMS/DiExtraBundle/DependencyInjection/Compiler/LazyServiceMapPass.php'

If I comment the 3 following lines in JMSSerializerBundle :
/if (class_exists('JMS\DiExtraBundle\DependencyInjection\Compiler\LazyServiceMapPass')) {
return new \JMS\DiExtraBundle\DependencyInjection\Compiler\LazyServiceMapPass($tagName, $keyAttributeName, $callable);
}/

it works ...

Sorry for the long feedback loop.
This issue is probably already solved.

(if not feel free to re open the issue or to comment here)

Thanks
