I am trying to list form fields using the following code. There is no issue for 
a few PDF documents but for some I am getting the error - 
java.lang.NullPointerException.  

                String pdfSource = "SIMPLE IRA App 1.828247.101 &  Ret Acct 
Customer Agmt 1.830486.102 -- as of 6-6-08.pdf";
                try {

                FileOutputStream outputObj;
                PrintStream outputFile;
                        String fileName = pdfSource.replace(".","_") + ".txt";

                        outputObj = new FileOutputStream(fileName);
                        outputFile = new PrintStream(outputObj);

                        PDDocument document = PDDocument.load(pdfSource);

                        try {
                                if (document.isEncrypted()) {
                                        document.decrypt("");
                                }
                        } catch (Exception e) {
                                System.out.println("Failed to decrypt document 
#");
                        }

                        List list = 
document.getDocumentCatalog().getAcroForm().getFields();
                        PDField pdfield;

                        for (int i = 0; i < list.size(); i++)
                        {
                                pdfield = (PDField) list.get(i);
                                String fldName = pdfield.getPartialName();
                                outputFile.println(fldName);
                        }
                        document.close();
                        outputFile.close();
                } catch (Exception e) {
                        System.out.println("Error!" + e);
                }

Please let me know what the issue is.
