Can not convert files that have no extension

[GoogleCodeExporter]

What steps will reproduce the problem?
1. launch the program below with mydoc.odt mydocout => the mydocout is a 
correct PDF (even if it has no extension)
2. rename mydoc.odt to mydoc
3. launch the program below with mydoc mydocout2 => error

What is the expected output? What do you see instead?
the expected output is mydocout2 as a correct PDF

Problem lies in org.artofsolving.jodconverter.OfficeDocumentConverter.convert :
DocumentFormat inputFormat = 
formatRegistry.getFormatByExtension(inputExtension);

=> because my input has no extension, it causes the error

Solution :
provide a org.artofsolving.jodconverter.OfficeDocumentConverter.convert(File 
inputFile, DocumentForm inputFormat, File outputFile, DocumentFormat 
outputFormat) method

Workaround : rename the file without extension to a file with extension

PLEASE NOTE : this bug does not occur under Windows but only with OO 3.2.1. 
under squeeze in headless mode

public static void main(String[] args) {
    OfficeManager officeManager = new ExternalOfficeManagerConfiguration().buildOfficeManager();
    try {
    File odt = new File(args[0]);
    File pdf = new File(args[1]);
        OfficeDocumentConverter converter = new OfficeDocumentConverter(officeManager);
        DocumentFormat pdfFormat = converter.getFormatRegistry().getFormatByExtension("pdf");
        converter.convert(odt, pdf, pdfFormat);
    } catch (Exception e) {
        throw new RuntimeException(e);
    } finally {
        officeManager.stop();           
    }
}
