com.oracle.svm.core.jdk.UnsupportedFeatureError: OperatingSystemMXBean

[RafaelCavazza]

We are trying to collect some runtime and system metrics using the com.sun.management.OperatingSystemMXBean.

Stack Trace:

@RafaelCavazza thanks for reporting the issue
we will take a look and get back to you

@RafaelCavazza I tried a simple sysout with GraalVM CE 21.0.0.2 and it worked
please provide specific reproduer :

import java.lang.management.ManagementFactory;
class Main{
    public static void main(String[] args) {
        var operatingSystemMXBean = (com.sun.management.OperatingSystemMXBean) ManagementFactory.getOperatingSystemMXBean();
        var freeMemory = operatingSystemMXBean.getFreePhysicalMemorySize();
        System.out.println(freeMemory);
    }
}

output

$ java Main.java 
861347840

Hi @mcraj017!

Thanks for the response.

I built the native-image using:
mvn clean package -DskipTests -Pnative

Then a ran the binary using: ./target/MY_PROJECT

My code:

public class App {
    public static void main(String[] args) {

        var operatingSystemMXBean = (com.sun.management.OperatingSystemMXBean) ManagementFactory.getOperatingSystemMXBean();
        var freeMemory = operatingSystemMXBean.getFreePhysicalMemorySize();
        System.out.println("Free memory:" + freeMemory);
    }
}

The error:

Exception in thread "main" com.oracle.svm.core.jdk.UnsupportedFeatureError: OperatingSystemMXBean methods
        at com.oracle.svm.core.util.VMError.unsupportedFeature(VMError.java:87)

@RafaelCavazza thanks I am able to reproduce it and it will be resolved in future releases

Hi guys!

Any update on this issue?

This will enable us to send environment metrics with OpenTelemetry using the native image.

hi @mcraj017 any ETA of this fix? Is there a potential work around?
