I am attempting to use PdfCopyFields to concatinate and fdfmerge.
When I run the following code I get the exception:
ExceptionConverter: java.lang.ClassCastException: com.lowagie.text.pdf.PRIndirectReference

Is this a known issue? Is there a work-around?

The code:
try {
ByteArrayOutputStream pdfConcatStream = new ByteArrayOutputStream();
OutputStream pdfStream = dest.getDestinationType();
PdfCopyFields appender = new PdfCopyFields(pdfConcatStream);
while (files.hasMoreFiles()) { //files is basically a list of byte[]
InputPDFFile currentFile = files.nextFile();
PdfReader formReader = new PdfReader(currentFile.getFile());
appender.addDocument(formReader);
}
appender.close();
PdfReader concatedFileReader = new PdfReader(pdfConcatStream.toByteArray());
PdfStamper stamp = new PdfStamper(concatedFileReader, pdfStream);
AcroFields form = stamp.getAcroFields();
byte[] fdf_in = data.getBytes();
FdfReader fdf = new FdfReader(fdf_in);
form.setFields(fdf);
stamp.close();
pdfConcatStream.close();
pdfStream.close();
}
catch (Exception e) {
