A couple of points to note, you need to close the iterator after use -
here is my preferred implementation
FeatureCollection collection = FeatureCollections.newCollection();
FeatureIterator iterator = collection.iterator(); // I like to go normal
java where possible
try {
while( iterator.hasNext() ){
collection.add( (Feature) iterator.next() );
}
}
finally {
collection.close( iterator );
}
