**Describe the bug** Trying to complete an empty Multipart Upload to AWS S3 fails with error: `Generic S3 error: Error performing complete multipart request: Client error with status 400 Bad Request: <?xml version="1.0" encoding="UTF-8"?> <Error><Code>MalformedXML</Code><Message>The XML you provided was not well-formed or did not validate against our published schema.</Message>...` This happens because the library sends no parts on the completion request. AWS S3 expects at least a single empty part (previously uploaded). **To Reproduce** Create an `AsyncWrite` from `put_multipart` of `AmazonS3` store and try to run `AsyncWriteExt::shutdown` without writing any data to it. **Expected behavior** The completion request returns successfully and and empty object is created **Additional context** AWS S3 does not impose any minimum part size for the last part of a completion request. -- This is an automated message from the Apache Git Service.
