      Description

        The Octane benchmarks have regressed 5-50% on all platforms when using 10-b39. The Octane benchmarks impacted are:

        • Octane-Crypto -41 to -52%
        • Octane-DeltaBlue -18 to -22%
        • Octane-Gbemu -19 to 32%
        • Octane-PdfJS -1 to -6%
        • Octane-Raytrace -2 to -5%
        • Octane-Richards - 44 to -61%

        The regressions reproduce in triage (a repro run on the same machine).
        The regressions reproduce in re-triage (a repro run on a different machine).

        VMswap results indicate the cause is in the JKD (not the JVM).

        There's only one nashorn bugfix in b39: JDK-8193567
        Which is the suspected cause (not proven).
        Will need the Nashorn engineers to investigate.
