JMH 的 DTraceAsmProfiler 在 Mac 上失败并显示"[sudo：需要密码"

Question

我在MacOS上运行DTraceAsmProfiler的IDEA基准测试，它失败了这个错误:

Exception in thread "main" org.openjdk.jmh.runner.ProfilersFailedException: Profilers failed to initialize, exiting.
at org.openjdk.jmh.runner.Runner.internalRun(Runner.java:228)

... 2 more

我代码:

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，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
]

以前有人面对过吗?

我终于找到了解决方案:

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"
