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.
