[jira] [Created] (COMPRESS-485) Reproducible Builds: keep entries order when gathering ParallelScatterZipCreator

Hervé Boutemy created COMPRESS-485:
--------------------------------------

             Summary: Reproducible Builds: keep entries order when gathering ParallelScatterZipCreator
                 Key: COMPRESS-485
                 URL: https://issues.apache.org/jira/browse/COMPRESS-485
             Project: Commons Compress
          Issue Type: Improvement
          Components: Archivers
    Affects Versions: 1.18
            Reporter: Hervé Boutemy


currently, zip files created using ParallelScatterZipCreator have random order.
This is causing issues when trying to do Reproducible Builds with Maven MNG-6276

Studying ParallelScatterZipCreator, entries are kept sorted in memory in futures list: instead of writing each full scatter in sequence, iterating over futures should permit to write each zip entry in original order
