There is an incompatibility between Lucee and Adobe ColdFusion with cfpdf(action="getInfo");
In ACF, the returned struct includes the following properties:
PageRotations - an array of rototion values of 0, 90, 180, 270 for each page in the PDF
PageSizes - an array of structs with width and height values for each page in the PDF (taken from TrimBox)
In Lucee, the PageRotations and PageSizes properties are not returned at all.
For the benefit of others stumbling upon this issue I will provide the work-around code to leverage the PDFBox 2.0.16 library.
