  | True. You could address the scenario by catching the UnsupportedOperationException on Collection.add() and falling back to a default mechanism.

It doesn't quite work the way you describe.
The collection is first instantiated and then the values added.

We could hack it like you describe, but it wouldn't be very clean.
Maybe it is worth the ugliness for the ease of use? :-)
