Doctrine\ORM\Mapping\Driver\AttributeDriver extends Doctrine\Persistence\Mapping\Driver\AnnotationDriver.

AttributeDriver::isTransient resolves to AnnotationDriver::isTransient.

If a class has repeating attributes an error is thrown in AnnotationDriver:182 because $annot is an array.

namespace App\Entity;

use Doctrine\ORM\Mapping as ORM;

#[ORM\Index(columns: ['foo'])]
#[ORM\Index(columns: ['bar', 'baz'])]
#[ORM\Entity]
class Foo
{
 //...

Workaround: When the repeatable attributes trail non-repeatable ones of entityAnnotationClasses the method returns before the error occurs.
