Dawid Weiss commented on LUCENE-9922:
-------------------------------------
It's a bug, Robert. We should have the keys ordered - it also simplifies
reading that file.
> checksums files should use deterministic sort order?

> When regenerating, I notice some changed checksum files (when nothing
> actually changed).
> For example when regenerating ICU, it produced this diff: none of the
> checksums are changed but files are simply listed in a different order.
