Hi,

I have the same trouble. When I try to convert .doc to .pdf in linux, I have the next mistake:

Caused by: java.lang.NullPointerException

at com.cajamar.cb.fwk.wordutils.AsposeDocument.save(AsposeDocument.java:317)

In this linux machine, I use jdk 1.7 and Aspose 17.4.0. I do not understand why I have this problem because I use a version very recent.

Can you help me?
