The implementation of simple features in GeoTools is crippled by not
being fully namespace aware. It assumes that all properties of a simple
feature are in the same namespace as the feature type, and in some
places it just doesn't care about namespaces at all. You can see this
in, for example, SimpleFeatureImpl (one a many examples):
public Property getProperty(Name name) {
return getProperty( name.getLocalPart() );
}
I suspect that this might be causing your problem. As a consequence of
this defect, the "name" of your feature type collides with the (gml:)
"name" of gml:AbstractFeatureType.
Kind regards,
Ben.
