Description

I use the PDDocument in my application and noticed that the load method throws an IOException (Error: End-of-File, expected line) with certain PDF files like the one in the attachment.

 

My code:

 

protected List<String> getLocalPages(final Resource completeEditionResource, final Edition edition, final int firstPage) throws Exception {
        PDDocument document = null;
        try {
            final InputStream in = completeEditionResource.getInputStream();
            document = PDDocument.load(in, MemoryUsageSetting.setupTempFileOnly());
        }
        PdfUtils.disableImageCache(document);
        return splitAndSavePages(document, firstPage, completeEditionResource, edition.getPublishedDate());
        } finally {
            if (document != null) {
                document.close();
            }
            completeEditionResource.getInputStream().reset();
        }
}

 

Exception thrown:

 

java.io.IOException: Error: End-of-File, expected line

I successfully downloaded the PDF using FileUtils.copyInputStreamToFile from Apache Commons-IO just before PDDocument.load to verify that the inputStream was correct.
