issue with ksp and nested interfaces while using @ConfigurationProperties - works with kapt but not KSP

[brenol]

Expected Behavior

Application should run correctly, load configuration and not crash.

Actual Behaviour

Application crashes with the following error:

Message: Receiver class com.example.BaseConfiguration$Intercepted does not define or inherit an implementation of the resolved method 'abstract java.lang.String getHost()' of interface com.example.Other.
Path Taken: new MyClass(BaseConfiguration baseConfiguration)
        at io.micronaut.context.DefaultBeanContext.resolveByBeanFactory(DefaultBeanContext.java:2349)
        at io.micronaut.context.DefaultBeanContext.doCreateBean(DefaultBeanContext.java:2304)
        at io.micronaut.context.DefaultBeanContext.doCreateBean(DefaultBeanContext.java:2316)
        at io.micronaut.context.DefaultBeanContext.createRegistration(DefaultBeanContext.java:3127)

Steps To Reproduce

Run ./gradlew run on the repository.

There is also a kapt configuration on build.gradle.kts. Just comment KSP and change to kapt.

@dstepanov look to this, pls. Confirmed it is a bug. Checked it with micronaut 4.8.3. Errro with introspection:

Classes structures:

fun main(args: Array<String>) {
	ApplicationContext.builder().banner(false)
		.eagerInitConfiguration(true)
		.eagerInitSingletons(true)
		.build()
		.start()
}

@Controller("/")
open class MyClass(private val baseConfiguration: BaseConfiguration) {
	init {
		println("Host: ${baseConfiguration.host}")
		println("Port: ${baseConfiguration.port}")
	}

	@Get
	fun test() {
		println("Host: ${baseConfiguration.host}")
		println("Port: ${baseConfiguration.port}")
	}
}

@ConfigurationProperties("base")
interface BaseConfiguration : Other {
	val port: Int
}

interface Other {
	val host: String
}

BaseConfiguration$Intercepted (left is KSP, right KAP):

$BaseConfiguration$Intercepted$Definition$Exec:

$BaseConfiguration$Intercepted$Definition

KSP added this line: DefaultAnnotationMetadata.registerAnnotationType($micronaut_load_class_value_0());
KAPT: DefaultAnnotationMetadata.registerAnnotationDefaults($micronaut_load_class_value_0(), Map.of("bean", false, "iterable", false));

@dstepanov maybe this is another bug
