--------------------------------
Resolution: Implemented
Fix Version/s: Jena 2.10.2
This is out-of-date. LARQ is replaced by jena-text, and that does keep the index in sync.

> LARQ used not to update the Lucene index as RDF statements were added/removed from a Jena Model.
> LARQ is currently extending StatementListener [1] to keep a Lucene index in sync with a Jena Model, however this notification mechanism is not applicable in the case of SPARQL Update requests.
