nmethod::oops_do_marking_epilogue always runs verification code

    Details

    • Subcomponent:
      gc
    • Resolved In Build:
      b94

      Backports

        Description

        We waste up to a few milliseconds every root scanning GC pause, by calling cur->verify_oop_relocations(). This is unnecessary in product builds since the verification uses asserts, which are only enabled in debug builds.
