Strange caching-error

[Gladhon]

Hi I'm using the HandlerCallback like this

class AbstractProduct implements ProductInterface
{

   /**
     * @Serializer\HandlerCallback("xml", direction="serialization")
     */
    public function serialize2Xml(XmlSerializationVisitor $visitor, $value)
    {
      ...
    }
}

The first time, it run's like expected. But all in all other Runs it ignore's the custom handler callback.
If I touch the File, it run's okay for one time...

Could you open this on schmittjoh/serializer? Unfortunately, I can't copy it over automatically.

Thanks!
