[Ajaysankaran]

When trying to upload a stream to S3Proxy, it throws the error message as mentioned below. The stream is uploaded using S3AsyncClient from aws-java-sdk

S3 Proxy Version: 2.6.0
AWS Java SDK Version: 2.30.9

Error Details

• Initially it threw the below error:

org.gaul.s3proxy.S3ProxyHandler - Unknown header x-amz-trailer with URI *****

• After S3Proxy is configured to ignore unknown headers, it throws the below error

Content-Length mismatch, actual: 2052 expected 2000

• The above error is coming from TransientStorageStrategy | L: 198

[JulienBenoitSonos]

Checksum validation has been enabled by default in AWS SDK for Java 2.30.0.
It can be disabled by setting those options when building the S3 Client

        .requestChecksumCalculation(RequestChecksumCalculation.WHEN_REQUIRED)
        .responseChecksumValidation(ResponseChecksumValidation.WHEN_REQUIRED)
