Description

QueryFactory.create("PREFIX  rdfs: <http://www.w3.org/2000/01/rdf-schema#> ASK { SELECT * { ?class a rdfs:Class . } }").cloneQuery().toString()

produces

PREFIX  rdfs: <http://www.w3.org/2000/01/rdf-schema#>

ASK
WHERE
  { PREFIX  rdfs: <http://www.w3.org/2000/01/rdf-schema#>
    
    SELECT  *
    WHERE
      { ?class  a  rdfs:Class }
  }

which is invalid SPARQL syntax (note the second PREFIX).
