Andy Seaborne created JENA-1216:
-----------------------------------
Summary: xsd:integer literals with leading/trailing whitespace not
handled as values.
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.
