Entity with "date_immutable" field returned from database has DateTime instead of DateTimeImmutable

Bug Report

Q	A
BC Break	no
Version	2.7.1

Summary

Entity with "date_immutable" field returned from database has DateTime instead of DateTimeImmutable. If I change the annotation to "datetime_immutable" it works fine. I use Mysql engine if it matters.

Current behavior

How to reproduce

declare(strict_types=1);

namespace App\Entity;

class Test
{
    /**
     * @var int
     *
     * @ORM\Column(type="integer", nullable=false, options={"unsigned": true})
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    private $id;

    /**
     * @var \DateTimeImmutable
     *
     * @ORM\Column(name="`from`", type="date_immutable")
     */
    private $from;

    public function getFrom(): \DateTimeImmutable
    {
        return $this->from;
    }
}

$this->repository = $entityManager->getRepository(Test::class)->find(1)->getFrom();

this throw exception:

Return value of App\Entity\Test::getFrom() must be an instance of DateTimeImmutable, instance of DateTime returned

Expected behavior

The expected behavior is that it would be a DateTimeImmutable object :smile:

Have similar error - with Repository->findOneByField (createQueryBuilder) returning the values from DB.

Cannot assign DateTime to property App\Entity\Post::$createdAt of type ?DateTimeImmutable

Have to make field to be DateTime in order to work normally with entity. :( Really unexpected behavior, considering that it DateTimeImmutable was generated by make:entity so should work by default.

try

    #[ORM\Column(name: 'created_at', type: 'datetime_immutable' .....

@gimler can you reproduce the issue with a unit test?
