To Javier, Ed, Huisheng and Sebastian: excuse me if I did not reply earlier. There have been (and still are) discussions at JBoss about the ongoing plans. Today we made an announcement on the subject: the jBPM 5 Request for Comments. As described in the announcement jBPM 5 is an initiative based in the combined experiences of jBPM and Drools Flow. jBPM 4 is still an open topic which we want to discuss openly through the jbpm-dev maling list.
