GetAll is not callable when using @DBusBoundProperty on a List<DBusPath> property

[tutetaki]

Given the following dbus interface and implementation:

@DBusInterfaceName("dev.tutetaki.FruitManager")
public interface FruitManager extends DBusInterface {

    List<DBusPath> ListFruits();

    @DBusBoundProperty(type = PropertyFruitType.class)
    List<DBusPath> getFruits();

    public static interface PropertyFruitType extends TypeRef<List<DBusPath>> {
    }
}

public class FruitManagerImpl implements FruitManager {

    @Override
    public List<DBusPath> ListFruits() {
        return List.of(
                new DBusPath("/dev/tutetaki/FruitManager/1"),
                new DBusPath("/dev/tutetaki/FruitManager/2"),
                new DBusPath("/dev/tutetaki/FruitManager/3")
        );
    }

    @Override
    public List<DBusPath> getFruits() {
        return ListFruits();
    }

    @Override
    public String getObjectPath() {
        return "/dev/tutetaki/FruitManager";
    }
}

The property "Fruits" returns list of DBusPath correctly when requesting:

• the dbus method ListFruits via the java method ListFruits()
• the dbus property Fruits via the java method getFruits()
• the dbus property Fruits via the java method Get()

But not when invoking GetAll created by the library

public static void main(String[] args) throws DBusException {
    BasicConfigurator.configure();

    DBusConnection dbus = DBusConnectionBuilder.forSessionBus().build();
    FruitManager fruitManager = new FruitManagerImpl();
    dbus.exportObject(fruitManager.getObjectPath(), fruitManager);

    dbus.requestBusName("dev.tutetaki.FruitManager");


    Properties remotePropObj = dbus.getRemoteObject(
            "dev.tutetaki.FruitManager",
            "/dev/tutetaki/FruitManager",
            Properties.class);

    // outputs a result OK
    // >>> [/dev/tutetaki/FruitManager/1, /dev/tutetaki/FruitManager/2, /dev/tutetaki/FruitManager/3]
    Object getResult = remotePropObj.Get("dev.tutetaki.FruitManager", "Fruits");
    System.out.println(getResult);

    // Error
    Object getAllResult = remotePropObj.GetAll("dev.tutetaki.FruitManager");
    System.out.println(getAllResult);
}

> Task :MainFruit.main() FAILED

The issue appears to be around DBusBoundPropertyHandler.java#L125. The type of Object val is java.util.ImmutableCollections$ListN rather than the TypeRef PropertyFruitType?

I have pushed my sample here https://github.com/tutetaki/sample-dbus-object/blob/master/src/main/java/dev/tutetaki/MainFruit.java
