It might be related to the document restrictions. If > so, could the exception message reflect that? the field definition in the AcroForm is wrong as the field root is defined as a dictionary and not as an array as it's required by the PDF spec. How was the form created? I'm asking because if I create such form using Adobe LiveCycle Designer (there is an XFA definition in your form) the field root is OK i.e. it's an array. Could you open an issue at https://issues.apache.org/jira/browse/PDFBOX? I think we shold fix that as Adobe Reader and another viewer I tested can open the form just fine. So we should do the same.
