Itext Aspose.words and Coldfusion

We have been using aspose.words in a coldfusion mx7 environment. We noticed recently that creating pdfs in coldfsuion using cfdocument tag stopped working after installing the aspose jar files in cfusionmx7/lib. The problem could only be remedied by removing the itext-1.4.2.jar file.
The Coldfusion error message looks like:

500 com.lowagie.text.pdf.PdfContentByte.createGraphics(FFFFLcom/lowagie/text/pdf/FontMapper;)Ljava/awt/Graphics2D;

We also noticed that in the cfusionmx7/lib folder there is an itext.jar file as standard.
Is the itext-1.4.2 jar file required and how can we resolve this issue?

Thank you for considering Aspose. I will notify our Java developer and he will reply to you as soon as possible.

iText library used only in demo project to demonstrate (experimental) doc-to-pdf conversion. So you can freely remove it.

Many thanks for the quick response
