There will be a hibernate.properties file in the jbpm core download. We need to update that, as during the build the properties for the datasource are picked from there and updated into hibernate.cfg.xml. I have messed around too much with my core to guide you to exact solution. But I was able to stop the replacement of data by modifying the build file.
