Yes place is correct. Putting test before or after stream parsing
depends on whether you want to count failures happening during parsing
process or not.
What is the order of features returned by fc.getFeatures().iterator() is
a good question.
I think iterator will return them in the same order they have been
digitized because FeatureCollection is backed by an ArrayList which is
an ordered array of features,
but the contract of fc.getFeatures().iterator() do not guarantee
anything about the order.
You can test this way :
print(feature.getID());

Oh, I did not remember, glad to know it has a second life ;-)
