[GR-34103] Shutdown hooks not called when -H:-ParseRuntimeOptions is set

[mbien]

Hello!

It appears that -H:+UnlockExperimentalVMOptions -H:-ParseRuntimeOptions and --install-exit-handlers are not compatible with each other.

If -H:-ParseRuntimeOptions is set during build, the shutdown hooks won't run on sig TERM.

Tested with Graalvm CE 22.0.2

reproducer:

package repro.graalsignals;

import java.util.List;

public class Graalsignals {

    // run with: 'target/graalsignals -Dpropkey=hello'
    // then kill process (SIGTERM) and check if the shutdown task ran
    public static void main(String[] args) throws InterruptedException {

        System.out.println("-Dpropkey=" + System.getProperty("propkey"));
        System.out.println("args: " + List.of(args));
        Runtime.getRuntime().addShutdownHook(new Thread(() -> System.out.println("shutdown hook called")));

        int n = 0;
        while (true) {
            Thread.sleep(1000);
            System.out.println("sleeping "+n++);
        }        
    }
}

Hi @mbien,
Thank you for reaching out to us.
We're currently taking a look into this. I will get back to you regarding this shortly

[selhagani]

When the -H:-ParseRuntimeOptions flag is specified, VMRuntime.initialize() isn't executed, which prevents startup hooks from working. These hooks are necessary for implementing the --install-exit-handlers flag.

Our team is looking into this issue. I'll keep you posted with any new findings.
