PDFMergeUtility error invalid stored block lengths

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.
