--------------------------------------
Summary: createDescendantFont throws 'Invalid font type:
COSName{Font}' when reading pdf
Key: PDFBOX-4770
URL: https://issues.apache.org/jira/browse/PDFBOX-4770
Project: PDFBox
Issue Type: Bug
Components: PDModel, Text extraction
Affects Versions: 2.0.11
Environment: Java 8, macOS Mojave 10.14.6
Reporter: Samuel Litster
Our system needs to extract text from pdfs. It's been working for over a year,
but today we started seeing errors when we tried to process some pdfs. This has
only affected a small number of pdfs so far, but when it does come up we are
unable to extract the text. Following is the pertinent part of the stacktrace:

We have no control over the content of the pdfs, but we have to be able to
extract the text from them. Is there a workaround for this or some way to
configure PDFBox to handle this properly?
The offending pdfs are over 60 MB so I can't attach one to this issue.
