DefaultFeatureResults.getBounds(Query) inefficiencies
-----------------------------------------------------

                 Key: GEOT-1229
                 URL: http://jira.codehaus.org/browse/GEOT-1229
             Project: GeoTools
          Issue Type: Task
          Components: core main
    Affects Versions: 2.3.0
            Reporter: Andrea Aime
         Assigned To: Andrea Aime
             Fix For: 2.3.1


When the backing feature source returns null DefaultFeatureResults calls 
reader(), which returns fully populated features, when only the geometric 
attributes are required. If there are many attributes, or if attribute parsing 
is expensive (think shapefile dbf files) this is quite a bottleneck.
Get a reader with only the geometry attributes instead.
