Use zero_filled optimization for young gen regions when committing young regions

XMLWordPrintable

    • gc

      With JDK-8226731 the young regions can be initialized as "dirty" (= value 0), as with that change the "young_card" value is not required any more.

      I.e. when committing regions, on the on_commit handler for the card table should not do anything for young regions.

      This (i.e. doing nothing in this case) improves startup time.
