You could use the following modification:

but _dyaLine is not visible.

docx4j relies on Apache POI's HWPF to read a binary .doc, and it is in POI that a getter for _dyaLine is required.

Be aware that doc importing to docx is more a very basic proof of concept than anything else.

If you want to convert doc to docx, preserving a range of features, I'd suggest you use LibreOffice/OpenOffice via JODConverter.
