    • Type: Bug
    • Resolution: Won't Fix
    • Priority: P2
    • None
    • Affects Version/s: 25.0.2, 26
    • Component/s: core-libs

      For JDK26+20... After JDK-8369656, there are reasonably large performance regressions in Renaissance-FutureGenetic on all platforms (Linux-x64, macOS-x64, win-x64, macOS-aarch64, linux-aarch64):

      -5.7% on Linux-x64
      -2.9% on macOS-x64
      -7.6% on win-x64
      -7.7% on macOS-aarch64
      -3.2% on Linux-aarch64

      Regression isolated to jdk-26+20-2057 , which only contains JDK-8369656

      That bug fix was also backported to 25.0.2-b03 with JDK-8370311. I can confirm that the same regressions exhibit in that build as well.
