GTn00b,
I think you'll find that the actual instance of
SimpleFeatureCollection returned by FeatureCollections.newCollection()
is a MemoryFeatureCollection, so it's not surprising the behavior has
not changed when you create a MemoryFeatureCollection directly. I'm
not recommending that you use MemoryFeatureCollection, since it orders
features by feature id, not by insertion order into the collection.
The LeanFeatureCollection maintains the insertion order of features,
but is unfortunately not yet part of the official GeoTools release.

Start uncovering the many advantages of virtual appliances
and start using them to simplify application deployment and
accelerate your shift to cloud computing.
