one of the fields now is

> The appearance handling for forms in 1.x is limited and does not reflect all
> settings possible for form fields. In addition the current code is not very
> modular and does not follow the box model used for form fields.
> Unfortunately only the basics of form handling are defined in the PDF spec.
> The details like padding of boxes, text placement etc. have to be determined
> by looking at how Adobe forms are generated.
> Update: The file from PDFBOX-2310 has bad rendering which might be related?
