There was a problem hiding this comment.
Assuming that Product.quantity is of type Integer, the type of builder.sum( productRoot.get( Product_.quantity ) ) is Expression<Integer>, and the Tuple should contain an Integer and not a Long.
So I believe this assertion is incorrect, and that there's no bug here.
