> The {{position_}} field is initialized as -1, but the file writer class
> begins writing and aligning the format without updating the position, so this
> results in an extra byte written. This was reported in
> https://github.com/apache/arrow/issues/2559. A bit disturbing that this was
> not caught in unit tests
