>                 Key: JENA-1216
>                 URL: https://issues.apache.org/jira/browse/JENA-1216
>             Project: Apache Jena
>          Issue Type: Bug
>          Components: ARQ
>    Affects Versions: Jena 3.1.0
>            Reporter: Andy Seaborne
>            Assignee: Andy Seaborne
>             Fix For: Jena 3.1.1

> This throws an exception:
> {noformat}
>         Node n = SSE.parseNode("' 1'^^xsd:integer") ;
>         NodeValue.makeNode(n) ;
> {noformat}
> Once you know that, it's quite easy to cause the problem from SPARQL:
> {noformat}
> PREFIX :  <http://example/> .
> PREFIX xsd:     <http://www.w3.org/2001/XMLSchema#>
> # whitespace in the lexical form.
> :s :p " 1"^^xsd:integer .
> {noformat}
> and any query with a FILTER that uses the value of the literal.
> {noformat}
> SELECT *
> WHERE {
>       ?s ?p ?o .
>       FILTER ( ?o != 9 )
> }
> {noformat}
> It affects xsd:integer and derived types, not other datatypes.
> Because Turtle short form for integers does not generate this situation, it is masked to some extent.
