docx4j traversalutil finds no TextElements in the Paragraph node

Question

Edit: I know what a NullPointerException is, the problem is, that docx4j don't finds any elements in the Paragraph Node.

I'm trying to get the first element of the Text Class in a paragraph.

ClassFinder finder = new ClassFinder(P.class);
    new TraversalUtil(model.getWordMLPackage().getMainDocumentPart(),
            finder);
    finder.results.stream().forEach(
            elem -> {

                ClassFinder findfirsttext = new ClassFinder(Text.class);
                new TraversalUtil(elem, findfirsttext);
                Text tt=((Text)findfirsttext.results.get(0));
                System.out.println("asdf"+tt.getValue());

            });

but

                    Text tt=((Text)findfirsttext.results.get(0));

always results in a NullPointerException. Because the util doesn't find text elements in the Paragraph.

Since I'm parsing a valid document every Paragraph should contain at least one Text element.

Looking at code here, you dont have any element in arrayList and you are trying to getValue from null and hence end up in NullPointerException.
