David Ruszkai updated JENA-1863:
--------------------------------
Description:
*Description*
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}
Probably caused by:
