Jira issue originally created by user twistedlogic:

    /****
     * @ORM\ManyToOne(targetEntity="ClubBoardPost", inversedBy="children")
     * @var ClubBoardPost
     */
    protected $parent;

$criteria = Criteria::create()->where(Criteria::expr()->isNull('parent'));
$this->boardPosts->matching($criteria);

[output]
Cannot match on Fubles\CoreBundle\Entity\ClubBoardPost::parent with a non-object value. Matching objects by id is not compatible with matching on an in-memory collection, which compares objects by reference.

[first analysis]
@SqlExpressionVisitor:69 It seems like this check pretends that the value must be an object, maybe do you need to exclude NULL values only if association is nullable?
