Timo,
It's a bug. You are using the API right [low level API]. I've raised a
JIRA JENA-32 to make sure it does not get lost. (Too late here to fix
today)

Hi.
Same problem with Node.ANY :
DataSource dataSource = DataSourceImpl.createMem();
Node subject = Node.createURI(TEST.NS);
Node predicate = Node.createURI(RDFS.label.getId());
Node object = Node.createAnon();
dataSource.asDatasetGraph().add(new Quad(Quad.defaultGraphIRI, subject,
predicate, object));
dataSource.asDatasetGraph().deleteAny(Node.ANY, subject, Node.ANY,
Node.ANY);
I am using the SPI, since the lower level integration seems to be
enough. I am writing Jean support for another RDF abstraction layer, the
stuff of the higher level API is not needed.

Hi Timo,
I am having issues with the following code
DataSource dataSource = DataSourceImpl.createMem();
Node subject = Node.createURI(TEST.NS);
Node predicate = Node.createURI(RDFS.label.getId());
Node object = Node.createAnon();
dataSource.asDatasetGraph().add(new Quad(Quad.defaultGraphIRI,
subject, predicate, object));
dataSource.asDatasetGraph().deleteAny(null, subject, null, null);
The last line throws the following Exception :
java.lang.NullPointerException

Am I using the API wrong?
You're using the SPI, not the API (the model / resource stuff). Unlike
the API, where you use 'null' to match anything, the SPI uses Node.ANY
(hence your issue).
Out of interest, why are you using the SPI?
