             Summary: TDB round trip failures on 63bit integers
                 Key: JENA-363
                 URL: https://issues.apache.org/jira/browse/JENA-363
             Project: Apache Jena
          Issue Type: Bug
          Components: TDB
    Affects Versions: TDB 0.9.4
            Reporter: Dave Reynolds


The following example code attempts to store a large (63 bit) xsd:integer in a TDB instance.

  public void temp() throws Exception {
    String BASE = "http://example.com/test#";
    String lex63 = "5823355717404272516";

    Dataset ds = TDBFactory.createDataset("data/tdb");
    Model m = ds.getDefaultModel();

    Literal l = m.createTypedLiteral(lex63, XSDDatatype.XSDinteger);
    Resource r = m.createResource(BASE + "i").addProperty(RDF.value, l);

    System.out.println("Val = " + r.getProperty(RDF.value).getObject());
  }

This returns:

Val = -13309399667890300^^http://www.w3.org/2001/XMLSchema#integer 

A similar truncation occurs for xsd:long but strangely not for xsd:int.
