> I have come across some portfolio PDFs that have many attachments / embedded
> files, but Tika is not detecting or extracting them as it does with some
> other portfolio PDFs. The issue may be that these files have a multilevel
> EmbeddedFiles name tree that is not being handled properly by PDFBox.
> Here is the EmbeddedFiles structure of one of the PDF portfolios in question.
> Notice that the root EmbeddedFiles dictionary has a Kids array that only
> consists of intermediate dictionaries, with the actual Names array being one
> more level down.
