ADDITIONAL SYSTEM INFORMATION :
Reproducible on all OSs, Java starting from 16 (I didn't test earlier versions)

A DESCRIPTION OF THE PROBLEM :
This is not a duplicate of https://bugs.openjdk.org/browse/JDK-8273408
But it's very similar, that other bug was about having a record field of type that is generated using annotation processor.
This one is about having a record field of a generic type that is parameterized by a generated type: so instead of just `record Foo(GeneratedClass bar){}`, this time we need the following to reproduce the bug: `record Foo(List<GeneratedClass> bars){}`

Please see the following repo with a reproducer: https://github.com/nikita2206/jdk-records-generated-class-bug

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
- Create a maven project
- add Immutables library as a dependency
- create a file with the following interface:
import org.immutables.value.Value;
@Value.Immutable
public interface GeneratedClass {
  int foo();
}

- create a following file with the Java record:
import java.util.List;
public record JavaRecord(int foo, String bar, List<ImmutableGeneratedClass> thisWillFailCompilation) {}

- Run `mvn install`

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
This project should build
ACTUAL -
Getting the following compilation error:
