We're reading feature collections through the OracleDataStore. Calling method
feature() on an instance of FeatureCollection cause this error:

This only happen using Geotools version 2.2.0; running the same code on the
same data (same db) with version 2.2-RC3 we are able to read the feature
collection.
The attached file contains the code used.
Thank you
