JavaScript can't see Java properties/functions

[adikm]

Hey,
I'm playing around with GraalVM/Graaljs and I stumbled upon an issue. Snippet first:

class Application {
    public static void main(String[] args) {
        String script = "console.log(phone.number)";
        String script2 = "phone.call('Somebody')";
        Phone phone = new Phone();

        Context context = Context.create("js");
        context.getBindings("js").putMember("phone", phone);

        runScript(script, context);
        runScript(script2, context);
    }
    private static Value runScript(String script, Context context) {
        return context.eval("js", script);
    }
}
class Phone {
    public int number = 123;
    public void call(String name) {
        System.out.println("Calling...: " + name);
    }
}

When I execute the main method, that's what I'm getting:

In my pom.xml, there's graal-sdk included.

Note that your snippet will work when you make your Phone class public. I will let others comment on whether this behaviour is a bug or an intention.

Thank you @iamstolis. I missed that.
Going to leave it open though because as you said - it may be not intended.

It's intentional (and afaik in line with Nashorn).
While the Application class has access to Phone's members, the engine has not.
