ClassNotFoundException after Spring Boot Native Image compilation for s3/internal/ApplyUserAgentInterceptor.java

[klopfdreh]

Describe the bug

The reflect-config.json is missing in the s3 for services-custom/s3-transfer-manager/src/main/java/software/amazon/awssdk/transfer/s3/internal/ApplyUserAgentInterceptor.java which causes the Spring Boot Native build to throw a java.lang.ClassNotFoundException

Expected Behavior

When the reflect-config.json is added like in other packages and it is added via -H:ReflectionConfigurationResources to the native build, no java.lang.ClassNotFoundException is going to occur anymore.

Current Behavior

There is a java.lang.ClassNotFoundException during the runtime as the class ApplyUserAgentInterceptor.java can not be loaded JIT in a native image.

Reproduction Steps

Native compile a Spring Boot application like described here: https://aws.amazon.com/de/blogs/developer/graalvm-native-image-support-in-the-aws-sdk-for-java-2-x/ - note: the -H:ReflectionConfigurationResources=META-INF/native-image/software.amazon.awssdk/s3/reflect-config.json is not working anymore as it is missing.

Possible Solution

Add the reflect-config.json to the s3 package with the following content.

[
  {
    "name": "software.amazon.awssdk.transfer.s3.internal.ApplyUserAgentInterceptor",
    "methods": [
      {
        "name": "<init>",
        "parameterTypes": []
      }
    ]
  }
]

Additional Information/Context

N/A

AWS Java SDK version used

2.25.34

JDK version used

jdk17.0.10

Operating System and version

linux / ubi9-minimal:9.3-1612

[klopfdreh]

Same goes for software.amazon.awssdk.crt.s3.S3Client but I guess it is in a different package, so a separate reflect-config.json is required.

Edit: I created an issue in AWS CRT for this.

@klopfdreh acknowledged, marking as a bug.

[klopfdreh]

Hey @debora-ito maybe it would be a good idea to introduce the native support to the code as in Spring Cloud AWS - see: https://github.com/awspring/spring-cloud-aws/pull/856/files - this way there would be no issues even if you move the classes.

Edit: Saw that those classes are Spring related and can't be used in the SDK. Sorry for the noise.
