Description

Zero length putBlob is making two (duplicate) network calls instead of one.
This issue can be easily replicated by invoking putBlob operation with the zero-length blob.

ByteSource payload = ByteSource.empty();
Blob blob = blobStore.blobBuilder(blobName)
            .payload(payload)
            .contentLength(payload.size())
            .build();
blobStore.putBlob(containerName, blob);
