Our application generates a multiple page PDF by reading in a single page
"template" PDF form, populating the form fields with values from the database,
and adding a new page for each record from the database. The pattern is roughly:
Document document = new Document();
PdfCopy copy = new PdfCopy(document, new FileOutputStream(newFileName));
document.open();
PdfReader reader = new PdfReader(formFileName);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
PdfStamper stamper = new PdfStamper(reader, baos);
AcroFields form = stamper.getAcroFields();
form.setField(fieldName, fieldValue);
...
stamper.close();
Occasionally, calling stamper.close() results in the following
FileNotFoundException:
java.io.FileNotFoundException: .\forms\template.pdf (The system cannot find
the path specified)

I'm thinking that the template is still in use, and we are missing some
required "cleanup" method call(s), but I find it strange that the error only
occurs a small percentage of the time. Anyone else experience this?
