Hello.

Recently I've updated my PHP version to 8, Symfony to 5.2 and Doctrine 2.8.1.

I'm not sure if the problem is in ORM or DoctrineBundle, but I have an entity defined like so:

class Account {
    private AddressInterface|Address|null $address;
    // ... properties

    public function getAddress(): AddressInterface|Address|null {
        return $this->address;
    }
}

the only reason for using AddressInterface|Address is because of the huge code base and to be a helper to jump around the project.

The problem is that the proxy generates the following invalid PHP code:

    /**
     * {@inheritDoc}
     */
    public function setAddress(\App\Module\Location\Entity\AddressInterface|\App\Model\Entity\Address|?null $address): void
    {
        $this->__initializer__ && $this->__initializer__->__invoke($this, 'setAddress', [$address]);
        parent::setAddress($address);
    }

Using the ?Address notation works perfectly, but I can't say anything about Address|null as the profiler crashes to log (might be another problem in another place for this one, not related to Doctrine).

For now, I'll change back these entities to use the old form.

LE: just for fun, I've changed the return type of getAddress() to be string|int|null, and it generates string|int|?null. so it applies to primitives too.

well... after further investigation i reached to the conclusion that this issue is useless to be open here.

it was weird because i thought that doctrine/orm relies on ocramius/proxy-manager, but apparently, doctrine/migrations relies on friendsofphp/proxy-manager-lts which replaces ocramius/proxy-manager and they can't do anything unless ocramius/proxy-manager doesn't have full php 8 support.

oh boi, I love open source! [/sarcasm]
