Well the exception in this case seems to result from a call to
Feature.getName(), which affair for simple features isn't ever used. And in
the case of jdbc features we actually have a custom implementation based
directly on a jdbc ResultSet.
A few options here.
1. Implement getName() in ResultSetFeature and return null?
2. Ditch ResultSetFeature and use a normal feature that implements
getName().
