profiler - JMH 的 DTraceAsmProfiler 在 Mac 上失败并显示 '[sudo: a password is required'

Question

我正在使用 DTraceAsmProfiler 在 MacOS 上运行来自 IDEA 的基准测试它失败并出现此错误:

Exception in thread "main" org.openjdk.jmh.runner.ProfilersFailedException: Profilers failed to initialize, exiting.

我的代码:

public class BenchmarkRunner {

  public static void main(String[] args) throws RunnerException {
    Options opt = new OptionsBuilder()
            .include(CRHMBenchmark.class.getSimpleName())
            .warmupIterations(10)
            .warmupTime(TimeValue.seconds(1))
            .measurementIterations(10)
            .measurementTime(TimeValue.seconds(1))
            .addProfiler(DTraceAsmProfiler.class)
            .forks(5)
            .build();

    new Runner(opt).run();
  }
}

我也试过从终端运行它并得到同样的错误:

% java -jar target/benchmarks.jar CRHMBenchmark -f 2 -w 1s -r 1s -prof dtraceasm
Profilers failed to initialize, exiting.
[sudo: a password is required

以前有人遇到过吗？

最后我找到了解决方案:

sudo "/Users/stsypanov/Library/Java/JavaVirtualMachines/openjdk-17.0.1/Contents/Home/bin/java" -jar target/benchmarks.jar CRHMBenchmark -f 1 -w 1s -r 1s -prof dtraceasm -jvmArgsAppend "-XX:+UnlockDiagnosticVMOptions -XX:+PrintAssembly"
