Shenandoah: fragmentation metrics overhaul

XMLWordPrintable

    • gc
    • b16

        Current fragmentation computations have flaws:
         - fragmentation metrics are there to drive mutator behavior, but it captures evac-reserve;
         - external fragmentation do not count humongous objects spanning a single region
         - external fragmentation takes "total space" over all regions, while using "free space" only for completely empty ones

        These make gc/oom/TestThreadFailure.java fail with JDK-8241139 changes.
