Jira issue originally created by user @beberlei:
\Doctrine\ORM\Configuration creates an AnnotationDriver by default in the constructor.
However the documentation says this parameter is required and not optional.
In any case, the constructor creation could be moved into the getMetadataDriverImpl() as a lazy load, for this case the patch is attached.
