Error reading in Jena's own JSON-LD

Thu, 23 Jul 2015 08:02:43 -0700 

Hi,
I downloaded:
http://www.w3.org/People/Berners-Lee/card.rdf
read and dumped with Jena with:

Model m = RDFDataMgr.loadModel("tbl.rdf", Lang.RDFXML);

m.write(System.out,"JSON-LD");
then tried to read the JSON-LD with Jena RDFDataMgr and got the

following error:
Exception in thread "main" org.apache.jena.riot.RiotException: [line: 2,

col: 3 ] Relative IRI: @graph
