Hello @nicolas-grekas ,
I feel like these additions introduce a bug ?
With doctrine-bundle v2.14.0

Doctrine\ORM\Mapping\Embeddable" has already been autoconfigured and merge() does not support merging autoconfiguration for the same attribute

@adpeyre I don't know, please provide a reproducer in a new issue if you can (I installed doctrine-bundle with Symfony 7.3 successfully, which means I cannot reproduce).

Note that this error message is not found anywhere in Symfony 7.3 so I'm skeptical.

I think the person in my team hasn't updated their symfony properly to test 7.3.... This appears to be symfony 7.2 code... Sorry Nicolas.

Hi @nicolas-grekas
We are getting issue on Symfony 7.2.6 & Drupal 11
Symfony\Component\DependencyInjection\Exception\RuntimeException: You have requested a synthetic service ("kernel"). The DIC does not know how to construct this service. in Symfony\Component\DependencyInjection\ContainerBuilder->createService() (line 1093 of vendor/symfony/dependency-injection/ContainerBuilder.php).
apigee/apigee-devportal-kickstart-drupal#733

Any plans to release this fix for Symfony 7.2 ?

You might experience something else. The attached patch is for 7.3.

Yes, I am experiencing this error on Symfony 7.2 & Drupal 11

Symfony\Component\DependencyInjection\Exception\RuntimeException: You have requested a synthetic service ("kernel"). The DIC does not know how to construct this service. in Symfony\Component\DependencyInjection\ContainerBuilder->createService() (line 1093 of vendor/symfony/dependency-injection/ContainerBuilder.php).

I am asking, can we look for this issue in Symfony7.2 ?
Do you want me to create a issue for this ?

You'd better ask Drupal before, I don't see how this can be related to Symfony itself. It'd rather look like a bug in the way Symfony is used.

Thanks @nicolas-grekas for clarifying things here.
