Suppose there is a bean A which has a field producer for some type X and a bean B which extends A.
Then add a portable extension with @Observes ProcessedAnnotatedType<?> pat and inside it invoke pat.configureAnnotatedType().
A reproducer is here - https://github.com/manovotn/core/tree/reproduce2903

In such a scenario, there will be two definitions of bean X as if the producer field was inherited.

The offending line seems to be the invocation of pat.configureAnnotatedType(); removing that makes the test pass.
