[Loggable] Loggable entity is instantiated without constructor

[ezkimo]

I am using an own loggable entity which contains a one to many relation for the changed data instead of writing the data as serialized array in a text column. As you all know doctrine one to many relations are stored in a collection, which is instantiated in the constructor of the entity.

<?php
declare(strict_types=1);
namespace Marcel\Entity;

use Doctrine\Common\Collections\ArrayCollection;
use Doctrine\Common\Collections\Collection;
use Doctrine\ORM\Mapping as ORM;

...
#[ORM\OneToMany(targetEntity: HistoryValue::class, mappedBy: "parent", cascade: [ "persist", "remove" ])]
protected Collection $data;

public function __construct()
{
    $this->data = new ArrayCollection();
}
...

In \Gedmo\Loggable\LoggableListener::createLogEntry in line 296 a new history entity is created via metadata s instantiator. The instantiator creates a new entity instance via reflection without executing the constructor. In the shown case the data property will never be instantiated as ArrayCollection. That makes it difficult to use normalized, individual entity classes for loggable entries.

A possible solution could be instantiating the entities directly with the new keyword or via ReflectionClass::newInstance(). This would avoid follow up exceptions when persisting relations in a loggable entity.
