Hi, I m using buildVersion=2.1.6-SNAPSHOT of blazegraph.
This query seams be bugged:
CONSTRUCT { <http://this> <http://type> <http://obj> ; <http://label> "This is a test" ; <http://where> <http://not.void> . } WHERE { ?s ?p ?o . <http://test> ?p ?o }
Blazegraph response:
ERROR: SPARQL-QUERY: queryStr=CONSTRUCT { ; "This is a test"; . } WHERE { ?s ?p ?o . ?p ?o } java.util.concurrent.ExecutionException: java.util.concurrent.ExecutionException:

If I try to change that query to this second one:
CONSTRUCT { ?s <http://type> <http://obj> ; <http://label> "This is a test" ; <http://where> <http://not.void> . } WHERE { ?s ?p ?o . <http://test> ?p ?o }
it's working fine.
Anyway, I think that the first construct should be allowed, it seems to follow the SPARQL1.1 query grammar.
Edit:
If there aren't triples these match with the Where patter of the construct, the construct run as well.
if for example before this construct you run this update:
INSERT DATA { <http://test> <p> <o>}
then the construct will go into error.
So if the where patter of the construct match some triple, Blazegraph returns that error.
