Symfony version(s) affected

7.3.0

Description

I'm migrating from Symfony 6.4 to 7.3 and my classes are not correctly deserializing after the upgrade due to the fact that I'm having my types hinted in @var PHPDoc segments instead of one single block with @param.

This doesn't work anymore (emails are deserialized into an array of plain PHP array s):

class ContactDto {

    public function __construct(
        /** @var ContactEmailDto[] */
        protected ?array  $emails = null,
    )
    {
    }
}

but it starts working once I change it to:

class ContactDto {

    /**
     * @param ContactEmailDto[]|null  $emails
     */
    public function __construct(
     
        protected ?array  $emails = null,
    )
    {
    }
}

I don't see any valid reason for dropping support of @var

How to reproduce

1. Create a dummy class similar to

class ContactDto {

    public function __construct(
        /** @var ContactEmailDto[] */
        protected ?array  $emails = null,
    )
    {
    }
}

2. Try to deserialize it and see that the emails were deserialized into an array of plain PHP arrays instead of instances of ContactEmailDto
