AsyncProfiler Java API crashes the JVM

[omarmahamid]

Hi,

I'm using this peace of code (which is Java API for Async Profiler)

<dependency>
            <groupId>tools.profiler</groupId>
            <artifactId>async-profiler</artifactId>
            <version>2.9</version>
        </dependency>

        AsyncProfiler profiler = AsyncProfiler.getInstance();

        // Start profiling
        profiler.execute("start,event=cpu,file=startup-cpu-profile.html,interval=1000000,simple");

        // Code to be profiled
        Set<String> set = new HashSet<>();
        long start = System.currentTimeMillis();
        for (int i = 0; i < 100000000; i++) {
            boolean in = set.contains(String.valueOf(i).toUpperCase());
            BigDecimal bigDecimal = new BigDecimal("-21.2");
            bigDecimal.divide(new BigDecimal("-213.22"));
        }
        System.out.println("took: " + (System.currentTimeMillis() - start));

        Thread.sleep(10000);

        // Stop profiling
        profiler.execute("stop,file=startup-cpu-profile.html");

and I got that the JVM crash

hs_err_pid83592.log

also when I'm using other permutation

if I replace

profiler.execute("start,event=cpu,file=startup-cpu-profile.html,interval=1000000,filter");

It works but the flamegraph is empty

any ideas ?

According to the crash log, the bug happened with JDK 17.0.8 on macOS/ARM in StubRoutines::SafeFetch32.

That's the exact duplicate of #817 and has been already fixed.
