> Triples of the form (N-Triples syntax):

> can not be parsed. Error message:
> java.lang.IllegalArgumentException: Invalid object: null
> at
> org.apache.clerezza.rdf.core.impl.TripleImpl.<init>(TripleImpl.java:50)
> at
> org.apache.clerezza.rdf.rdfjson.parser.RdfJsonParsingProvider.addValuesToGraph(RdfJsonParsingProvider.java:130)
> While such triples may not be very interesting semantically, they are
> nevertheless valid RDF.
> If there is a triple of the form (the blank node appears as the subject)
> _:a <http://example.org/prop2> "Hello" .
> in the graph the parsing succeeds.
