Andy Seaborne commented on JENA-733:
------------------------------------
This is very old behaviour. The documentation should be fixed to state it can
be a "narrower" class.
> Long typed literals report class java.lang.Long but return java.lang.Integer

> 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.
