    Resolution: Fixed

This was already added at some point (it's currently on line 253 of PDFMergerUtility.java), just cleaning up JIRA.

> I'm seeing exceptions like this when merging certain documents:
> java.lang.NullPointerException
>         at org.pdfbox.util.PDFMergerUtility.mergeAcroForm(PDFMergerUtility.java:412)
>         at org.pdfbox.util.PDFMergerUtility.appendDocument(PDFMergerUtility.java:210)
>         at org.pdfbox.util.PDFMergerUtility.mergeDocuments(PDFMergerUtility.java:148)
> It looks like it's fine just to add this check on line 208 of PDFMergerUtility.java, unless there's a deeper cause:
> -        else
> +        else if( srcAcroForm != null )

> I had this same problem and found the same result.  There are certain PDFs which, for reasons unknown to me, cause this NullPointerException and don't get appended to the resulting PDF file.  I downloaded and modified the PDFMergerUtility.java file in PDFBox-0.7.4-dev-20070525 and now I get the expected behavior: no NPE and the PDF gets appended to the resulting PDF.
> I don't have any insight regarding any deeper causes for the NPE, but I can confirm that this suggested patch worked for me.
