>
> Key: JENA-479
> URL: https://issues.apache.org/jira/browse/JENA-479
> Project: Apache Jena
> Issue Type: Bug
> Components: ARQ
> Reporter: Elli Schwarz
> Assignee: Andy Seaborne
>
> 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 }
> This bug may be similar to JENA-378.
