Unable to provide third party value extractor when the bean definition is not returning ValueExtractor

[tobias-bahls]

Expected Behavior

When I create a Bean via Factory in order to provide JsonNullableJakartaValueExtractor like this:

@Factory
private class JsonNullableJakartaValueExtractorFactory {
    @Singleton
    fun nullableExtractor(): JsonNullableJakartaValueExtractor {
        return JsonNullableJakartaValueExtractor()
    }
}

I expect the ValueExtractor to be picked up by Jakarta Validation.

Actual Behaviour

The registration of the value extractor throws an error:

Caused by: java.util.NoSuchElementException: No value present
	at java.base/java.util.Optional.orElseThrow(Optional.java:377)
	at io.micronaut.validation.validator.extractors.ValueExtractorDefinition.<init>(ValueExtractorDefinition.java:48)
	at io.micronaut.validation.validator.extractors.DefaultValueExtractors.<init>(DefaultValueExtractors.java:83)

Found a workaround for this issue that fixes it for now by manually adding JsonNullableJakartaValueExtractor to DefaultValidatorConfiguration

@Context
class JsonNullableValueExtractorRegistrar(private val config: DefaultValidatorConfiguration) {
    @PostConstruct
    fun registerJsonNullableValueExtractor() {
        config.addValueExtractor(JsonNullableJakartaValueExtractor())
    }
}
