// After some debugging, I found that the issue came from
// [`UnitOfWork#createEntity`](https://github.com/doctrine/doctrine2/blob/bba5ec27fbbe35224be48878a0c92827ef2f9733/lib/Doctrine/ORM/UnitOfWork.php#L2512-L2528) with #406 (DCOM-96).
// When initializing the proxy for `$first` (during the `DDC2931User#getRank()` call), the ORM attempts to fetch also `$second` again
// via [`ObjectHydrator#getEntity`](https://github.com/doctrine/doctrine2/blob/bba5ec27fbbe35224be48878a0c92827ef2f9733/lib/Doctrine/ORM/Internal/Hydration/ObjectHydrator.php#L280)`,
// but the hint `doctrine.refresh.entity` contains the initialized proxy, while the identifier passed down
// is the identifier of `$second` (not a proxy).
// `UnitOfWork#createQuery` does some comparisons and detects that in fact, the two objects don't correspond,
// and therefore marks the entity as "to be detached"
// Load Entity in second order // Load Entity in second order
