ReflectionEnumProperty throws error on AttributeReader::getPropertyAnnotations()

BC Break	no
Version	2.11.0

Summary

An Error "Internal error: Failed to retrieve the reflection object" is thrown when calling AttributeReader::getPropertyAnotations because the inherited function ReflectionProperty::getAttributes() is not called on the original reflection property in the ReflectionEnumProperty class.
In my specific case I 'm using custom annotations I have to read for custom behaviour. When trying to retrieve the custom annotations the error occurs.

Current behavior

When trying to fetch all or a specific annotation of an entity property, the call fails with an error "Internal error: Failed to retrieve the reflection object".

How to reproduce

enum Suit: string {
    case Hearts = 'H';
    case Diamonds = 'D';
    case Clubs = 'C';
    case Spades = 'S';
}

#[Entity]
class Card
{
    /** ... */

    #[Column(type: 'string', enumType: Suit::class)]
    #[AnyCustomAnnotation(param: 'bla')]
    public $suit;
}

/** ... */

// @var \Doctrine\ORM\EntityManager
$metadata = $objectManager->getClassMetadata(Card::class);

foreach ($metadata->fieldMappings as $field => $mapping) {
    $property = $metadata->getReflectionProperty($field);
    // @var Doctrine\ORM\Mapping\Driver\AttributeReader
    $isCustom = $reader->getPropertyAnnotation($property, AnyCustomAnnotation::class);
    /** ... */
}

Expected behavior

The expected behaviour should return the property attributes like ReflectionProperty::getAttributes() is supposed to. A possible solution could be extending the ReflectionEnumProperty class with an inherited getAttributes method, that will return the attributes from the original reflection property.

class ReflectionEnumProperty extends ReflectionProperty
{
    ...
    /**
     * {@inheritDoc}
     */
     public function getAttributes(?string $name = null, int $flags = 0): array
     {
         return $this->originalReflectionProperty->getAttributes();
     }
}
