Martynas Jusevičius commented on JENA-1935:
-------------------------------------------

{{QueryTransformOps}} exhibits the same problem:

{code:java}

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

{code}
