Version	2.13
PHP version	7.1.27

Summary

Getting Inheritance error when trying to create entity manager:

EntityManager::create($connection, $config);

Current behavior

When I'm trying to create EntityManager instance, I get the next error:

Declaration of Doctrine\ORM\Proxy\ProxyFactory::skipClass(Doctrine\Persistence\Mapping\ClassMetadata $metadata) must be compatible with Doctrine\Common\Proxy\AbstractProxyFactory::skipClass(Doctrine\Common\Persistence\Mapping\ClassMetadata $metadata)

How to reproduce

Create \Doctrine\ORM\Configuration object instance:

$cache = new FilesystemAdapter('rest');
$entitiesPaths = ['path/to/entities'];
$config = ORMSetup::createAnnotationMetadataConfiguration($entitiesPaths, $isDevMode);
$config->setResultCache($cache);

Then creating the \Doctrine\DBAL\Connection:

$connection = DriverManager::getConnection([
                'wrapperClass' => PrimaryReadReplicaConnection::class,
                'driver' => 'pdo_mysql',
                'keepReplica' => true,
                'primary' => [
                    'user' => $config->get('master.username'),
                    'host' => $config->get('master.hostname'),
                    'password' => $config->get('master.password'),
                    'dbname' => 'db',
                ],
                'replica' => [
                    [
                        'user' => $config->get('slave.username'),
                        'host' => $config->get('slave.hostname'),
                        'password' => $config->get('slave.password'),
                        'dbname' => 'db',
                    ]
                ]
            ]
        );

And to create Doctrine\ORMEntityManager instance:

$entityManager = EntityManager::create($connection, $config);

After this, error is occurred.

Expected behaviour

Doctrine\ORMEntityManager to be created.

@derrabus commented on GitHub (Oct 27, 2022):

There's something odd here. The signature of the AbstractProxyFactory::skipClass() method in doctrine/common 3.4.3 looks like this:

abstract protected function skipClass(\Doctrine\Persistence\Mapping\ClassMetadata $metadata);

Now, your error message prints the following signature:

Doctrine\Common\Proxy\AbstractProxyFactory::skipClass(Doctrine\Common\Persistence\Mapping\ClassMetadata $metadata)

Note that the namespace of the ClassMetadata class is different. That's an old namespace that we don't use anymore for quite a while now. I don't know where the AbstractProxyFactory class you are using is coming from, but I can tell for sure it's not the one from the doctrine/common 3.4.3 package.

I'm moving this issue to support now because it's apparently not a bug on our side.
