Roman "Exile" Just a Metaphore
I thought everyone knew that the "Roman Exile" was just a metaphor. That while the Romans politically subjugated the Jews, banned them from, and eventually destroyed, Jerusalem, and generally made life miserable for Jews in the Land of Israel, they did not physically exile them as the Assyrians and Babylonians did. But apparently not.
A good discussion of the this issue an be found on the blog of The Magnes Zionist. I recommend it.
