-------------------------------------
This issue is likely causing https://issues.apache.org/jira/browse/JENA-2360
> TDB doesn't preserve lexical form of integer-valued decimals
> ------------------------------------------------------------
>
> Key: JENA-2361
> URL: https://issues.apache.org/jira/browse/JENA-2361
> Project: Apache Jena
> Issue Type: Bug
> Components: TDB2
> Affects Versions: Jena 5.1.0
> Reporter: Damien Obrist
> Priority: Minor
>
> The following sample code reproduces the issue:
>
> {code:java}
> public static void main(String[] arguments) {
> try {
> FileUtils.deleteDirectory(new File("sample-data"));
> } catch (IOException e) {
> throw new RuntimeException(e);
> }
> Dataset dataset = TDB2Factory.connectDataset("sample-data");
> Txn.executeWrite(dataset, () -> {
> // TDB: code wrongly prints out "2.0"
> Model model = dataset.getDefaultModel();
> // in-memory: code correctly prints out "2"
> //Model model = ModelFactory.createDefaultModel();
> model.add(
> ResourceFactory.createResource("http://www.test.com/my-graph";),
> RDF.type,
> ResourceFactory.createTypedLiteral("2", XSDDatatype.XSDdecimal)
> );
> System.out.println(model.listStatements().next().getObject().asLiteral().getLexicalForm());
> });
> } {code}
> The behaviour is as follows:
> * When running the code with Jena 5.1.0, it wrongly prints out "2.0"
> * When running the code with Jena 5.0.0, it correctly prints out "2"
> * When running the code using the in-memory model instead of the TDB one,
> then with both Jena 5.0.0 and 5.1.0, it correctly prints out "2"
> It seems that the problem happens when writing the triple, not when reading
> it: if the above code is modified and run with Jena 5.0.0 to store, and with
> Jena 5.1.0 to read the triple, then it correctly prints out "2".
