Empty Grid in 8.0.2

Hi folks,

I am really excited to upgrade to Vaadin 8. But I just can't get the grid to display anything even in the most basic example (using Vaadin archetype) on neither Firefox or IE11. The only thing I see is Grid border (See attached)

In another caveat I was able to display the scrollbar on the right side if I populate grid with a lot of values but still no columns and rows. Here is my code

@Override protected void init(VaadinRequest vaadinRequest) {

final VerticalLayout layout = new VerticalLayout();
Label label = new Label("My Grid:");
ArrayList<Person> persons = new ArrayList<>();
persons.add(new Person());
Grid<Person> grid = new Grid<>();
grid.setItems(persons);
layout.addComponents(label, grid);
setContent(layout);
}

static class Person { String name = "Name"; String lastName = "LastName"; }
