I was making some changes to try and improve performance and I started gett=
ing this exception:

The PDFGenerator.java:885 line is the line that sets up the HELVETICA font:

             try {
                    font =3D PDType1Font.HELVETICA;
                    fontBold =3D PDType1Font.HELVETICA_BOLD;
             } catch(Exception e) {
                    throw new ProductRequestException("Unable to find Fonts=
/arial.ttf", e);
             }

I wasn't getting this before, what would be causing pdfbox to try and write=
 out a cache file?

Thank you,
Ray
