>             Project: Apache Jena
>          Issue Type: Bug
>          Components: ARQ

> *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}
> OR
> {code:java}
> new SelectBuilder().addWhere(createVariable("subject"), "a", createVariable("object")).buildString()
> {code}
> will create the following query
> {code:java}
> SELECT  *
> WHERE
>   { ?subject  a                     ?object}
> {code}
> Probably caused by:
>  [https://github.com/apache/jena/commit/6570c25be8c6e958a5647a7d2c1e23466498b332]
> *Summary*
> The formatting of the query is invalid when the rdf:type predicate is present.
> *Steps to reproduce*
> Check the result of
> {code:java}
> new SelectBuilder().addWhere(createVariable("subject"), "a", createVariable("object")).buildString()
> {code}
> *Expected results*
> {code:java}
> SELECT  *
> WHERE
>   { ?subject  a  ?object}
> {code}
> *Actual results*
> {code:java}
> SELECT  *
> WHERE
>   { ?subject  a                     ?object}
> {code}
