Different behavior between VM an dart2js version / Uncaught exception in js_helper

[MikeMitterer]

Just want to let you know there is a problem between the VM and the dart2js version.

abstract class Name {
    String get firstName;
}

// Fails if compiled to JS - it works with "extends"!!!!!!
class NameImpl implements Name {

  @override
  String get firstName => "Mike";
}

class ExampleModule extends dice.Module {
    configure() {
        register(Name).toInstance(new NameImpl());

    }
}

main() async {
    final dice.Injector injector = new dice.Injector(new ExampleModule());
    final Name name = injector.getInstance(Name);

   print(name.firstName);
}

This should also work but fails in dart2js

abstract class Name {
    String get firstName;
}

class NameImpl extends Name {

  @override
  String get firstName => "Mike";
}

class ExampleModule extends dice.Module {
    configure() {
        //register(Name).toInstance(new NameImpl());

        // concrete implementation!
        register(NameImpl);

    }
}

main() async {
    final dice.Injector injector = new dice.Injector(new ExampleModule());
    final Name name = injector.getInstance(NameImpl);

    print(name.firstName);
}
