G1: Improve thread sizing for evacuation failure

XMLWordPrintable

    • gc

      JDK-8254167 tracks which regions failed evacuation; but probably thread sizing could be improved if we know how much work in total needs to be done.

      E.g. assuming we have better per-region thread distribution (JDK-8256265), the number of threads could be determined by actual work not just by number of regions.
