Greetings. After evaluating 3.0.2, I would like to continue development using the latest and (hopefully) greatest 3.1 version. In the release notes there is a reference to migration tips:
Configuration: The jbpm.properties file is replaced by a file called jbpm.cfg.xml. The easiest way to upgrade jBPM is to convert the properties you had in your jbpm.properties to the section DEPRECATED JbpmSessionFactory CONFIGURATIONSat the bottom of the file jbpm.cfg.xml.
