How to test retry option with S3CrtRetryConfiguration

[karunakaran-ti]

I am using Spring boot Java application and using AWS amazon SDK.

    implementation('software.amazon.awssdk.crt:aws-crt:0.24.0')
    implementation 'software.amazon.awssdk:s3-transfer-manager:2.20.119'

I am using below code to generate S3AsyncClient with retry configuration. When I do upload using this client, it should retry if there is an issue. But I don't see any retry is triggered if there is a failure.

        S3CrtAsyncClientBuilder s3CrtAsyncClientBuilder =
                    S3AsyncClient.crtBuilder().credentialsProvider(creds).region(region);

        S3CrtRetryConfiguration s3CrtRetryConfiguration = S3CrtRetryConfiguration.builder().numRetries(s3UploadMaxRetries).build();
        s3CrtAsyncClientBuilder.retryConfiguration(s3CrtRetryConfiguration);

        S3AsyncClient s3CrtAsyncClient = s3CrtAsyncClientBuilder.build();

Any suggestions would be helpful and let me know if I miss any configuration.
