    XMLWordPrintable

    Details

    • Subcomponent:
      gc
    • Resolved In Build:
      b25
    • CPU:
      x86

      Description

      This has been fixed in shenandoah/jdk.

      It deserves a separate bug for jdk/jdk, because it may result hard to find bug, and probably need to be backported down to 8u.

      Current AArch64's code is correct.
