NoSuchElementException when getting annotation arguments from FB's infer

See original GitHub issue

If we declare a dependency on FB’s Infer:

api("com.facebook.infer.annotation:infer-annotation:0.18.0")

And declare a class using an Infer annotations:

import com.facebook.infer.annotation.Nullsafe;

@Nullsafe(Nullsafe.Mode.STRICT)
public interface D {
}

And we try to get the information about the annotation used in the KSP processor:

(resolver
  .getClassDeclarationByName("com.example.D")!!
  .annotations.first().arguments[1].value!! as KSAnnotation)
  .arguments

We get a NoSuchElementException rather than the Set we expect:

[ksp] java.util.NoSuchElementException: Collection is empty.

I am having the same issue using kotlinx.serialization annotations. Classes annotated with @Serialized is producing the same error stack trace
