      Description

      The query

      SELECT * WHERE {
        ?person rdf:type <http://example.com/Person> .
        OPTIONAL { ?person <http://example.com/image> ?image } .
        ?person rdfs:label ?label .
      }
      

      is equivalent to the query

      SELECT * WHERE {
        ?person rdf:type <http://example.com/Person> .
        ?person rdfs:label ?label .
        OPTIONAL { ?person <http://example.com/image> ?image } .
      }
      

      However, currently it is not rewritten, there seems to be an index-off-by-one problem in ASTJoinGroupOrderOptimizer.
