Reproduction Steps

import software.amazon.awssdk.services.s3.S3AsyncClient;
import software.amazon.awssdk.services.s3.model.*;

import java.util.Collections;

public class S3LifecycleManager {

public static void addAutoDeleteLifecycleRule(S3AsyncClient s3AsyncClient, String bucketName) {
    LifecycleExpiration expiration = LifecycleExpiration.builder()
            .days(15)
            .build();

    LifecycleRule rule = LifecycleRule.builder()
            .id("AutoDeleteAfter15Days")
            .filter(LifecycleRuleFilter.builder().prefix("").build()) // Applies to all objects
            .status(ExpirationStatus.ENABLED)
            .expiration(expiration)
            .build();

    BucketLifecycleConfiguration configuration = BucketLifecycleConfiguration.builder()
            .rules(Collections.singletonList(rule))
            .build();

    PutBucketLifecycleConfigurationRequest request = PutBucketLifecycleConfigurationRequest.builder()
            .bucket(bucketName)
            .lifecycleConfiguration(configuration)
            .build();

    try {
        s3AsyncClient.putBucketLifecycleConfiguration(request).join();
        System.out.println("Lifecycle rule applied successfully to bucket: " + bucketName);
    } catch (Exception e) {
        System.err.println("Error applying lifecycle rule to bucket " + bucketName + ": " + e.getMessage());
        e.printStackTrace();
    }
}

Hello @bameline,

Thank you for reporting the issue. In AWS SDK for Java v2.30.0, we introduced changes to the S3 client that adopts new default integrity protections, as announced in discussion #5802.

I was able to validate that the below code sample works fine with the latest MinIO version - RELEASE.2025-06-13T11-33-47Z, which indicates that you may be using an older version of MinIO which didn't support the changes introduced in Java SDK v2.30.0 onwards. You may want to validate it against the latest version for MinIO, when using Java SDK v2.30.0 or above.

Main.java

package org.example;

import software.amazon.awssdk.auth.credentials.AwsBasicCredentials;
import software.amazon.awssdk.auth.credentials.StaticCredentialsProvider;
import software.amazon.awssdk.regions.Region;
import software.amazon.awssdk.services.s3.S3AsyncClient;
import software.amazon.awssdk.services.s3.model.*;

import java.net.URI;

import java.util.Collections;

public class Main {
    public static void main(String[] args) {

        AwsBasicCredentials credentials = AwsBasicCredentials.create(
                "****",
                "****"
        );

        S3AsyncClient s3AsyncClient = S3AsyncClient.builder()
                .endpointOverride(URI.create("http://localhost:9000"))
                .credentialsProvider(StaticCredentialsProvider.create(credentials))
                .region(Region.US_EAST_1)
                .forcePathStyle(true)
                .build();
        addAutoDeleteLifecycleRule(s3AsyncClient, "putbuketlifecycleconfiguration**");

    }

    public static void addAutoDeleteLifecycleRule(S3AsyncClient s3AsyncClient, String bucketName) {
        LifecycleExpiration expiration = LifecycleExpiration.builder()
                .days(15)
                .build();

        LifecycleRule rule = LifecycleRule.builder()
                .id("AutoDeleteAfter15Days")
                .filter(LifecycleRuleFilter.builder().prefix("").build())
                .status(ExpirationStatus.ENABLED)
                .expiration(expiration)
                .build();

        BucketLifecycleConfiguration configuration = BucketLifecycleConfiguration.builder()
                .rules(Collections.singletonList(rule))
                .build();

        PutBucketLifecycleConfigurationRequest request = PutBucketLifecycleConfigurationRequest.builder()
                .bucket(bucketName)
                .lifecycleConfiguration(configuration)
                .build();

        try {
            s3AsyncClient.headBucket(HeadBucketRequest.builder().bucket(bucketName).build()).join();
            s3AsyncClient.putBucketLifecycleConfiguration(request).join();
            System.out.println("Lifecycle rule applied successfully to bucket: " + bucketName);
        } catch (NoSuchBucketException e) {
            System.err.println("Bucket does not exist: " + bucketName);
        } catch (Exception e) {
            System.err.println("Error applying lifecycle rule to bucket " + bucketName + ": " + e.getMessage());
            e.printStackTrace();
        }
    }
}

Kindly let me know if this helps. If you continue to encounter the problem I would suggest to reach out to the third-party provider for further support on this issue.
