I have the same problem too, I think. In a test program running on a Windows
machine it works fine but when I run the same program on Linux, the soffice
process takes 99.9% CPU usage and my application can't connect to OpenOffice to
transform documentos to PDF.

This is the test class that tries to launch soffice with -headless mode:


package com.ooffice;
