 Review comment:
   `type=application/x-java-archive` does not seem to be needed. Can you explain why it is a good idea to specify it? I would keep the `Expect` header because I remember that it was not supported in previous versions of Flink. Also this discussion is relevant: https://support.urbanairship.com/hc/en-us/articles/213492003--Expect-100-Continue-Issues-and-Risks
