--------------------------------

    Attachment: PDFBOX-724.patch

Line numbers in original report are after the patch for PDFBOX-699 has been applied.  Since this is only a few lines of code, it may be easier to just apply the patch by hand since the line numbers may not line up (depending on the order in which the patches are applied).

> On line 496 of PDFMergerUtility, "target" is cast as a COSObject without checking the type.  In some circumstances target will be a COSDictionary which will cause the following ClassCastException.
> java.lang.ClassCastException: org.apache.pdfbox.cos.COSDictionary
