-----------------------------------------
Thanks for your detailed text!
IMHO it's fine to add mockito. It's only for tests so no license problems.
2 or 3 are fine. 2 uses JUnit 4 and 3 uses JUnit 5.
Re testing, I have the ARLRDBD.TTF font on my system, it probably came with MS
Office.

I modified {{testPDFBox3747}} in PDFontTest.java to use that font but didn't
get an error with the existing code. Do you if you modify that test?
A possible explanation is that your font is a different one.

> Key: PDFBOX-5191
> URL: https://issues.apache.org/jira/browse/PDFBOX-5191
> Project: PDFBox
> Issue Type: Bug
> Components: PDModel
> Affects Versions: 2.0.21, 3.0.0 PDFBox
> Reporter: Larry Lynn
> Priority: Major
>
> PDFBOX-4882 fixed a bug that made isEmbeddingPermitted() too permissive. But
> it introduced a bug that made isEmbeddingPermitted() too restrictive for TTFs
> with OS2 table versions 0-2.
>
> TTFs with OS2 table versions 0-2 can have multiple permission bits set.
> According to the spec described in
> [https://docs.microsoft.com/en-us/typography/opentype/spec/os2#fstype]
> "in the event that more than one of bits 0 to 3 are set in a given font, then
> the _least-restrictive permission indicated take precedence_."
> Unfortunately, the current code essentially makes the most restrictive
> permission take precedence. This causes pdfbox to throw an error:
> "This font does not permit embedding"
> when attempting to process fonts that worked fine in pdfbox v2.0.20 and lower
