Resteasy tries to instantiate abstract classes since Quarkus 3.3

[balta3]

Describe the bug

I use an abstract base class for the Rest Application class in an common library, Quarkus 3.3 is suddenly trying to instantiate this class, Quarkus 3.2 is working as intended.

As a workaround, set quarkus.resteasy.ignore-application-classes to true

Expected behavior

Resteasy should not try to instantiate abstract classes and simply ignore them.

Actual behavior

Resteasy tries to instantiate an abstract class, failing with an exception at startup:

How to Reproduce?

1. Clone https:/balta3/Quarkus-AbstractApplicationReproducer
2. Run the application, it will fail to start
3. To see this is a regression, set the Quarkus version to 3.2.12.Final and run the application, it will not fail to start

Thanks for reporting.

The attached reproducer does not work at all unfortunately... It does not seem to be a properly configured Quarkus application

[geoand]

In any case, #41465 fixes the issue
