Description

Running the following code:
String updateString = "INSERT {} WHERE

{ ?x ?p [ ?a ?b ] }

";
UpdateRequest update = UpdateFactory.create(updateString);

UpdateProcessor up = UpdateExecutionFactory.createRemote(update,
"http://localhost:3131/ds/update");
up.execute();

Causes the Fuseki server to throw this error: 400 Encountered " "?" "? ""
This is caused by the client generating incorrect SPARQL with an extra ? (as viewed from the Fuseki log): INSERT { } WHERE

{ ?x ?p ??0 . ??0 ?a ?b }
