Subscribing to Forge events?

idk my name

The way I'm trying to do:

//I was just curious to extend (implement) SubscribeEvent.
forgeListener = new (Java.extend(SubscribeEvent, java.util.function.Consumer, {
    accept: function(event) {
        print(event.class.name)
        mc.fontRenderer.drawString("test", 0, 0, -16746560)
    }
}));

function registerForgeEvent(eventClass, listener) {
    activeModContainer = Loader.instance().activeModContainer();

    !activeModContainer && (activeModContainer = Loader.instance().getMinecraftModContainer());
    adaptedBus = new Reflector(MinecraftForge.EVENT_BUS);
    //Core issue: when a class has two the same methods but with different parameters Core calls the first one found (even with the wrong parameter count).
    registerMethod = MinecraftForge.EVENT_BUS.class.getDeclaredMethod("register", java.lang.Class.class, java.lang.Object.class, java.lang.reflect.Method.class, ModContainer.class);
    registerMethod.setAccessible(true);
    adaptedBus.listenerOwners.put(listener, activeModContainer);
    //adaptedBus.register(eventClass, listener, getMethod(listener, "accept"), activeModContainer);
    registerMethod.invoke(MinecraftForge.EVENT_BUS, eventClass, listener, getMethod(listener, "accept"), activeModContainer);
}

function unregisterForgeEvent(listener) {
    adaptedBus = new Reflector(MinecraftForge.EVENT_BUS);
    adaptedBus.unregister(listener);
}

But I get this error:

I copied the way of registering methods from https://github.com/MinecraftForge/MinecraftForge/blob/d3f01843f7e7a4f613b5e8113d381fd8747b4343/src/main/java/net/minecraftforge/fml/common/eventhandler/EventBus.java#L65
