[GR-72683][Native Image] VirtualThreadSchedulerMXBean is unavailable as it "is not a platform management interface"

[wilkinsona]

Describe the Issue

This was originally reported as a Spring Boot issue, but it fails with a plain Java application:

package com.example.demo;

import java.lang.management.ManagementFactory;
import jdk.management.VirtualThreadSchedulerMXBean;

public class DemoApplication {
	
	public static void main(String[] args) {
		System.out.println(ManagementFactory.getPlatformMXBean(VirtualThreadSchedulerMXBean.class));
	}
}

Using the latest version of GraalVM can resolve many issues.

• I tried with the latest version of GraalVM.

GraalVM Version

I believe Virtual Threads is still not supported in native image, I am correct @wirthi ?

[wirthi]

VirtualThreads should be fully supported by Native Image for Java Bytecode based languages (support is lacking for Truffle languages in Native Image).

In this case this might be a problem around MXBeans.

[christianhaeubl]

The MX bean part of virtual threads is currently not supported. There is an internal work-in-progress PR that adds this functionality but it needs some more work before it can be integrated.
