Issues with Grails PDF Renderer after using XWPF PDF Converter

[ilan18]

Existing Grails Code is as follows:

FileOutputStream os = new FileOutputStream(filename)
ITextRenderer renderer = new ITextRenderer()
configureRenderer(renderer)
org.w3c.dom.Document document = getTheDocument()
renderer.setDocument(document, grailsApplication.config.grails.serverURL)
renderer.layout()
renderer.createPDF(os)

Now added

org.apache.poi.xwpf.converter.pdf.PdfOptions options = org.apache.poi.xwpf.converter.pdfPdfOptions.create();
OutputStream outputStream = new FileOutputStream(fileNameWithDirectory)
PdfConverter.getInstance().convert(docxDocument, outputStream, options)
outputStream.close()

Now call the original code again. Get an Exception on line creating new ITextRenderer() :

java.lang.RuntimeException: Font 'Courier-BoldOblique' with 'Cp1252' is not recognized.
