public class DeltaWithFixedIterator extends org.apache.jena.graph.compose.Delta
Delta implementation that 'fixes' removals on iterators returned by .find(). Issue affects at least Jena 3.8.0 and likely earlier versions Calling .remove() on the returned iterator does not register a deletion record in Delta; instead it removes triples from the base model - which arguably defeats Delta's purpose by breaking its encapsulation.
