LINQ Reporting with JsonDataSource generates incorrect output for number type double using Java


I’m trying to create a word document replacing placeholder using LINQ Reporting Engine with JsonDataSource.
I’ve a problem with json number type (double). If I’ve a json property with value equal to 80.00 for example, the replacing result is -2147483648 (the minor number represented with 32 bit).
I tried with other number values with decimal difference from 0 (ex: 80.03) and the replacing result is correct.
Seems like the json number with all decimals to 0 is the problem.
How can Aspose replace correctly even json number with all 0 decimals value? For me a json value 80.0 differs from 80 because the type is different.

Here an example of Java code and document used:

String json = “{\n” +
““root”:\n” +
“{\n” +
““anagraficaObject”:\n” +
“{\n” +
““header”:{\n” +
““amount_percent” : 80.00,\n” +
““amount_double” : 456.123,\n” +
““amount_integer” : 123\n” +
“}\n” +
“}\n” +
“}\n” +

    FileInputStream input = new FileInputStream(ResourceUtils.getFile("classpath:TestDouble.docx"));
    Document doc = new Document(input);
    InputStream jsonIS = new ByteArrayInputStream(json.getBytes());

    JsonDataSource ds = new JsonDataSource(jsonIS);

    //ASPOSE report engine. Replace placeholders
    ReportingEngine engine = new ReportingEngine();
    //accepting missing attributes
    engine.buildReport(doc, ds, "root");

    doc.save("prova.docx", SaveFormat.DOCX);

Could you please attach your input Word document here for testing? We will investigate the issue on our side and provide you more information.

Isn’t possible to attach the “.docx" files, I convert this in ".pdf” and attach in topic (TestDouble.pdf).
Now attach the output file.
