Symfony version(s) affected

6.1.0

Description

PropertyInfo incorrectly detects collection type for types not documented in docblock since 6.1 version. Deserialization then fails with error

In ArrayDenormalizer.php line 40:
                                                                     
  [Symfony\Component\Serializer\Exception\InvalidArgumentException]  
  Data expected to be an array, int given.                                                                        

This is because before, ConstructorExtractor has been called, but now this is no longer the case. Now, PhpstanExtractor is called, which resolves types documented in phpdoc only. I've checked a bit why is this the case and looks like on 6.0, this line is triggered

How to reproduce

deserialize

{"id": 1, "variations": []}

into

namespace Haushalt\Bl\DomainBundle\Domain\Product\Entity;

final class Product
{
    /**
     * @param \stdClass[]   $variations
     */
    public function __construct(
        public int $id,
        public array $variations,
    ) {
    }

    public function getId(): int
    {
        return $this->id;
    }
}
