Description

When merging PDF's with the code:

PDFMergerUtility pm = new PDFMergerUtility();
File destPdf = File.createTempFile("TestFax_", ".pdf");
pm.setDestinationFileName(destPdf.getAbsolutePath());

for (File pdfFile:pdfFiles)

{ pm.addSource(pdfFile); }

try

{ pm.mergeDocuments(); return PDDocument.load(destPdf); }

catch (COSVisitorException e)

{ LoggerFactory.getLogger(getClass()).error("Merging PDF's", e); }

I get the exception:
