Andreas Lehmkühler resolved PDFBOX-2525.
----------------------------------------
Resolution: Fixed
The solution is to use the new overlay class instead of the deprecated one.
The new class had an issue with very small float values. The new class used
under some circumstances a floating point representation of small float values
which led to a malformed pdf. I've fixed that and now everything works fine.
Thanks for the report
