Bug Report
When building a GraalVM native image using dd-java-agent 1.61.0 or 1.61.1 with a Spring Boot 4 application that uses a Spring Kafka listener, the native image compilation fails with two fatal UnsupportedFeatureException errors.
Both errors are for inner classes of datadog.trace.bootstrap.instrumentation.java.concurrent.AsyncResultExtensions that are found in the image heap but are marked for runtime initialization.

Expected Behavior
Native image build completes successfully. The AsyncResultExtensions class and its inner classes should either be marked for --initialize-at-build-time in the agent's own native image configuration, or instantiation should not happen at build time.
Reproduction Code
Spring Boot 4 @KafkaListener method (the call stack in the error points directly to this path):
@KafkaListener(topics = "${sevensenders.kafka.consumer.topic}")
public void onMessage(ConsumerRecord<String, String> record, Acknowledgment acknowledgment) {
// handler body
}build.gradle (Paketo bootBuildImage config):
bootBuildImage {
builder = "paketobuildpacks/builder-noble-java-tiny"
buildpacks = [
'docker.io/paketobuildpacks/oracle',
'docker.io/paketobuildpacks/datadog:6.9.2', // or 6.9.0 — both fail
'urn:cnb:builder:paketo-buildpacks/java-native-image',
]
environment = [
"BP_NATIVE_IMAGE" : "true",
"BP_DATADOG_ENABLED": "true",
]
}Working version: docker.io/paketobuildpacks/datadog:6.4.0 → dd-java-agent 1.57.0 builds successfully with the same application and GraalVM configuration.
The first failing version has not been bisected exactly — 1.57.0 works, 1.61.0 and 1.61.1 both fail.
