Koen: "The jBPM designer and the runtime have one integration point: a configuration file called 'version.info.xml'. This file contains the version info of the runtime and the jar files that need to be on the classpath of a jbpm project in the gpd. If one of the jar files is not necessary anymore for various reasons, and it is removed from the runtime than it should also be removed from the file (if it is referenced in the file of course). "
