> 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.
