I think I looked at that a while back and didn't get anyplace. I just
tried to run the PrintFields app and I get a NullPointerException. I am
thinking the checkboxes in my form are just stored as black squares, not
completed form fields. Is that possible?
PDDocumentCatalog docCatalog = pdfDocument.getDocumentCatalog();
PDAcroForm acroForm = docCatalog.getAcroForm(); // returns null
List<PDFieldTreeNode> fields = acroForm.getFields(); //NPE here
