-----------------------------------

             Summary: WITH statement doesn't work
                 Key: JENA-1092
                 URL: https://issues.apache.org/jira/browse/JENA-1092
             Project: Apache Jena
          Issue Type: Bug
    Affects Versions: Jena 3.0.1
         Environment: Ubuntu 12.04
java version "1.8.0_66"
            Reporter: Osma Suominen


I found a possible problem with WITH statements in SPARQL Update queries. They 
do not seem to affect the INSERT clause in the expected way. The behaviour 
appears to have changed since Jena 3.0.0.

To reproduce:

1. Start Fuseki 1.3.1:

./fuseki-server --update --mem /ds

2. Create a triple in the <http://example.com/> graph:

PREFIX ex: <http://example.com/>
INSERT DATA { GRAPH ex: { ex:s ex:p ex:o }}

3. Run an update query using WITH:

PREFIX ex: <http://example.com/>
WITH ex:
INSERT { ex:s2 ex:p2 ex:o2 }
WHERE { ?s ?p ?o }

4. Check what you end up in the <http://example.com/> graph:

PREFIX ex: <http://example.com/>
SELECT * WHERE { GRAPH ex: { ?s ?p ?o }}

Result:

----------------------
| s | p | o |
======================
| ex:s | ex:p | ex:o |
----------------------

I would expect there to be the other triple { ex:s2 ex:p2 ex:o2 } too, but 
apparently that ends up in the default graph instead.

When using Fuseki 1.3.0 I get both triples in the <http://example.com/> graph, 
which I think is the correct behaviour.
