[DependencyInjection] dev class not found after 7.4 upgrade #62545
Description
Symfony version(s) affected
7.4.0
Description
After upgrading from Symfony 7.3.7 to 7.4.0, it seems that DI is failing whe trying to register classes when the parent class is missing.
The previous behaviour was quite useful e.g. when writing factory classes for Foundry.
AFAICT it was initially possible since this PR: #25932
How to reproduce
- Create a Symfony 7.3 project, add Doctrine ORM & Foundry
- Create an entity & a factory
- Run
APP_ENV=prod composer install --no-dev, it works - Run
composer install - Upgrade to Symfony 7.4
- Run
APP_ENV=prod composer install --no-dev, it now fails with the following error:
Executing script cache:clear [KO]
[KO]
Script cache:clear returned with error code 255

Possible Solution
No response
Additional Context
I created a reproducer here: https://github.com/jmsche/symfony-di-reproducer
You can see the difference between 7.3 & 7.4 branches when running APP_ENV=prod composer install --no-dev (the only difference between both branches is the Symfony 7.4 upgrade).
