These are the changes:

• feb4c27
• 95ad44c
• 147604a

We introduced them when we worked on #2176 and #2174, but they are causing a regression in Quarkus:
quarkusio/quarkus#47314

I will try to have a look and see if I can figure out what's going on, but, if we cannot find a solution, I think it's better to revert the changes and applies them again later

We actually have a solution for this, so I will just fix the issue
