Hi, I experienced some random NPE when merging documents using iText 5.5.x
and I managed to create a SSCCE. The exception is triggered only when using
PdfSmartCopy AND consolidateNamedDestinations is called on the reader AND
selectPages is called on the reader.
This is the document I used but it happened with others:
http://open-advice.org/Open-Advice.pdf
To keep the example short I didn't include multiple documents.
I think it is probably a bug but please let me know if there is anything
wrong with the code.
public static void main(String[] args) throws IOException,
DocumentException {
File outputFile = File.createTempFile("test", ".pdf");
RandomAccessSource ras = FACTORY
.createBestSource("/some-path/Open-Advice.pdf");
PdfReader reader = new PdfReader(new RandomAccessFileOrArray(ras),
null);
OutputStream outputStream = new FileOutputStream(outputFile);
Document pdfDocument = new
Document(reader.getPageSizeWithRotation(1));
PdfSmartCopy pdfCopy = new PdfSmartCopy(pdfDocument, outputStream);
pdfDocument.open();
reader.consolidateNamedDestinations();
reader.selectPages("1-50");
pdfCopy.addDocument(reader);
pdfCopy.freeReader(reader);
pdfCopy.close();
reader.close();
outputStream.close();
System.out.println("created " + outputFile.getAbsolutePath());
}
and this is the Stacktrace:
Exception in thread "main" java.lang.NullPointerException
