Description

The following SPARQL-Command fails when using the configuration setting native for sparql.strategy:

SELECT DISTINCT ?uri ?title ?children {
  GRAPH <http://host/context/graph> {
    ?uri a <http://www.w3.org/2004/02/skos/core#ConceptScheme> .
    OPTIONAL { 
      ?uri <http://www.w3.org/2000/01/rdf-schema#label> ?title . 
      FILTER (lang(?title) = 'en') 
    }
    BIND ( EXISTS { ?uri <http://www.w3.org/2004/02/skos/core#hasTopConcept> ?_top } AS ?children )
  }
}

when using sparql.strategy=memory the query works!
