Multiple inheritance mapped superclasses in different namespaces #12372
Description
Bug Report
On a Symfony 7 app, you can not have multiple inheritance mapped superclasses in different namespaces.
I have 2 abstract Entites in one namespace, one extends the other.
A concrete entity is in another namespace.
How to reproduce
Please check this demo repo: https://github.com/HaaseIT/SFDoctrineIssueDemonstrator
Error is seen with: bin/console doctrine:mapping:info
