[jira] [Comment Edited] (PDFBOX-3795) PDFMergeUtility error invalid
stored block lengths
[ https://issues.apache.org/jira/browse/PDFBOX-3795?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16016391#comment-16016391 ]

This fixes the bug, which has existed at least since 2008. I'll do more tomorrow. My current idea is to deprecate {{mergeInto}} and remove it in 3.0, and do something local instead. It is used only for merging and the usage for a COSStream is dangerous.
To repair existing *result* files merged this way - just get the metadata object, then do this:
{code}
document.getDocumentCatalog().getMetadata().getCOSObject().removeItem(COSName.FILTER);
{code}

> PDFMergeUtility fails with a DataFormatException when trying to merge PDF documents.
> Caused by: java.util.zip.DataFormatException: invalid stored block lengths
> I have attached 3 PDF documents
> * pdf-01.pdf
> * pdf-02.pdf
> * pdf-03.pdf
> The first two PDF documents are good. They can be merged. In fact they were used to create the third document (pdf-03.pdf).
> When trying to merge another PDF with the third document, the PDF merge utility throws the error.
