Could not initialize class com.oracle.truffle.api.vm.PolyglotRootNode

[lburgazzoli]

I have this snippet to invoke some java code from js from a native image:

import java.util.HashMap;
import java.util.Map;

import org.graalvm.polyglot.Context;
import org.graalvm.polyglot.Value;
import org.graalvm.polyglot.proxy.ProxyExecutable;
import org.graalvm.polyglot.proxy.ProxyObject;

public class Main {
    public static void main(String[] args) {
        try(Context ctx = Context.create()) {
            final Map<String, Object> proxy = new HashMap<>();
            proxy.put("sayHello", new ProxyExecutable() {
                @Override
                public Object execute(Value... arguments) {
                    if (arguments.length != 1) {
                        throw new IllegalArgumentException();
                    }

                    System.out.printf("Hello, %s\n", arguments[0].asString());
                    return null;
                }
            });

            ctx.getBindings("js").putMember("bean", ProxyObject.fromMap(proxy));

            ctx.eval("js", "bean.sayHello('World!')");
        }
    }
}

The build fails with:

Can you share your native-image command?

[lburgazzoli]

It is definef as part of the pom.xml

[cstancu]

Can you try adding also the --tool:regex dependency?

[lburgazzoli]

it does solve the issue, however the error is quite cryptic

[cstancu]

Yes, the error points to an incomplete class path which is essentially correct. However, we should catch earlier that you are using --language:js and should point out that you also need the --tool:truffle and --tool:regex dependencies or just add them automatically.

[olpaw]

@lburgazzoli this must have something to do with your use of native-image from within maven. If I run your sample from command line with --language:js -H:+JNI it works flawless.

@lburgazzoli btw, if you provide a full sample project I might be able to help you fix your pom file.

yes it does work, don't know what was wrong to be honest, thx for the support
