             Summary: java.util.zip.DataFormatException: invalid distance too far back
                 Key: PDFBOX-4227
                 URL: https://issues.apache.org/jira/browse/PDFBOX-4227
             Project: PDFBox
          Issue Type: Bug
    Affects Versions: 2.0.9
            Reporter: Michael Miller


I get a zip exception with the attached PDF file, which renders successfully in a couple of PDF viewers I tried.

ByteArrayInputStream pdfInputStream = new ByteArrayInputStream(pdfByteArray);
PDFMergerUtility merger = new PDFMergerUtility();
merger.addSource(pdfInputStream);

ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
merger.setDestinationStream(outputStream);
merger.mergeDocuments(MemoryUsageSetting.setupMainMemoryOnly());

 

PDF file attached.
