Micronaut fails to correctly generate Definition class and fails with ClassNotFoundException: <any>

[stepanv]

Expected Behavior

When using Micronaut with Lombok, when injecting a class that uses a builder class generated by Lombok's @SuperBuilder, Micronaut should be able to correctly generate its $Definition classes so that it doesn't fail during the runtime.

Actual Behaviour

Micronaut may generate invalid $Definition class file. In particular it may contain an invalid call

Argument.ofTypeVariable(<any>.class,"B")

which is what I see in the decompiled .class file.

The reality is that the Java classloader tries to load a class of a classname <any> which fails with exception

Caused by: io.micronaut.context.exceptions.BeanContextException: Error loading bean [io.micronaut.inject.generics.WildCardWithInheritanceLombokInject]: <any>

Steps To Reproduce

See my PR with a test that's failing with the reported error at: https://github.com/micronaut-projects/micronaut-core/pull/7974

where Micronaut for class

public class WildCardWithInheritanceLombokInject {
    // tests injecting field
    @Inject
    protected Action<?> action;

    interface Action<B extends MyDto.MyDtoBuilder<?, ?>> {
    }

    @Singleton
    static class IntegerAction implements Action<MyDto.MyDtoBuilder<?, ?>> {

    }

    @SuperBuilder
    static class MyDto {

    }

}

generates $WildCardWithInheritanceLombokInject$Definition.class containing

new Argument[] {
   Argument.ofTypeVariable(<any>.class, "B")
}

Interestingly, when I manually define the builder class in the MyDto class, the problem doesn't occur:

    @SuperBuilder
    static class MyDto {
        public static abstract class MyDtoBuilder<C extends MyDto, B extends MyDtoBuilder<C, B>> {
        }
    }

as Micronaut correctly generates

new Argument[] {
    Argument.ofTypeVariable(
        WildCardWithInheritanceLombokInject.MyDto.MyDtoBuilder.class,
        "B", 
        (AnnotationMetadata) null, 
        new Argument[] {
            Argument.ofTypeVariable(WildCardWithInheritanceLombokInject.MyDto.class, "C"),
            Argument.ofTypeVariable(
                WildCardWithInheritanceLombokInject.MyDto.MyDtoBuilder.class, 
                "B",
                (AnnotationMetadata) null, 
                Argument.ZERO_ARGUMENTS)
        })
}
