-------------------------------------------------------------
Indeed - SPARQL part is not affecting the situation.
Short example:
{noformat}
Model m = ModelFactory.createDefaultModel();
Literal litLong = m.createTypedLiteral(1L) ;
Literal litInt = m.createTypedLiteral(1) ;
Class<?> litLongJClass = litLong.getDatatype().getJavaClass();
Class<?> litIntJClass = litInt.getDatatype().getJavaClass();
Class<?> isLongJVClass = litLong.getValue().getClass();
Class<?> isIntJVClass = litInt.getValue().getClass();
System.out.printf("Long:\n") ;
System.out.printf("datatype.getJavaClass: %s\n", litLongJClass) ;
System.out.printf("literal.getValue class: %s\n", isLongJVClass) ;
System.out.printf("Integer:\n") ;
System.out.printf("datatype.getJavaClass: %s\n", litIntJClass) ;
System.out.printf("literal.getValue class: %s\n", isIntJVClass) ;

> Long typed literals in query results are returned as integers
> --------------------------------------------------------------
>
> Key: JENA-733
> URL: https://issues.apache.org/jira/browse/JENA-733
> Project: Apache Jena
> Issue Type: Bug
> Components: RDF API
> Affects Versions: Jena 2.11.2
> Reporter: Benno Willoweit
> Priority: Minor
>
> This is my first bug report ever so I hope I get this right. When retrieving
> query results with ARQ, long values are returned as Integers:
> {{QuerySulution qs;}}
> {{Literal l = qs.getLiteral("myVar");}}
> {{l.getDatatype().getJavaClass(); //returns java.lang.Long which is correct}}
> {{l.getValue(); //returns a java.lang.Integer object but it should return a
> java.lang.Long object according to the docs}}
> I have this problem with ARQ 2.11.2 which does not exist in the "affects
> version" drop down.
