@param wrong in Doctrine\ORM\PersistentCollection::__constructor Edit

When i try to generate a new PersistentCollection like this:
###############################################
$collection = new ArrayCollection();
new \Doctrine\ORM\PersistentCollection(
$this->getEntityManager(),
new ClassMetadata(''),
$collection
);
###############################################
i get an typ hinting error like
"Expected array, got "Doctrine\Common\Collections\ArrayCollection"

This could be fixed by changing the type hinting for the Doctrine\ORM\PersistentCollection::__constructor
_From:_
###############################################
/**

• Creates a new persistent collection.
  *
• @param EntityManager $em The EntityManager the collection will be associated with.
• @param ClassMetadata $class The class descriptor of the entity type of this collection.
• @param array $coll The collection elements.
  */
  public function __construct(EntityManager $em, $class, $coll)
  {
