NoSuchElementException when getting a default argument of the inner annotation type

[popovanton0]

When analyzing a function

@Kira
fun ExampleFunction3(
// ...

annotated with this annotation:

@Retention(AnnotationRetention.BINARY)
@Target(AnnotationTarget.FUNCTION, AnnotationTarget.CLASS)
public annotation class Kira(
    val customization: Customization = Customization(enabled = false, supplierImpls = false),
    val targetModule: String = "",
) {
    public annotation class Customization(val enabled: Boolean, val supplierImpls: Boolean)
}

and executing this code in the symbol processor:

val kiraAnn = getAnnotationsByType(Kira::class).first()
kiraAnn.customization

I get the following error:

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

However, with this annotation:

@Retention(AnnotationRetention.BINARY)
@Target(AnnotationTarget.FUNCTION, AnnotationTarget.CLASS)
public annotation class Kira(
    val customization: Customization = Customization(enabled = false, supplierImpls = false),
    val targetModule: String = "",
)

public annotation class Customization(val enabled: Boolean, val supplierImpls: Boolean)

error does not occur. Seems like a bug. Similar to #784?

ksp version = 1.6.21-1.0.5
kotlin version = 1.6.21

I created a branch in my repo that reproduces this behaviour. To reproduce, run this unit test. Input to the test is here. Code of the processor is here.
