-----------------------------------
Summary: Query builder creates query with wrong padding when
rdf:type is present
Key: JENA-1863
URL: https://issues.apache.org/jira/browse/JENA-1863
Project: Apache Jena
Issue Type: Bug
Affects Versions: Jena 3.14.0
Reporter: David Ruszkai
Creating a query with any QueryBuilder (SelectBuilder, AskBuilder etc.) when an
RDF.type predicate is present will result in a query that contains the
character 'a' followed by 19 spaces instead of a single 'a' (shortcut to the
RDF.type predicate) or "<http://www.w3.org/1999/02/22-rdf-syntax-ns#type>" (the
URI of the RDF.type predicate).
Example:
{code:java}
new SelectBuilder().addWhere(createVariable("subject"),
org.apache.jena.vocabulary.RDF.type, createVariable("object")).buildString()
{code}
OR
{code:java}
new SelectBuilder().addWhere(createVariable("subject"),
createURI("http://www.w3.org/1999/02/22-rdf-syntax-ns#type";),
createVariable("object")).buildString()
{code}
will create the following query
{code:java}
SELECT *
WHERE
{ ?subject a ?object}
{code}
