I have heard that the developers of "jBPM" have transferred to "Activiti BPMN 2" in recent times (ex: Tom).
I am wondering about is whether the support for jBPM will be over or not.. Besides, I would be glad to hear your ideas about if the improvements of Activiti BPMN will make it better or useful than jBPM as time goes on?
I would also like to know what are the pros/cons between them.
Activiti is an interesting project for several reasons:
They intend to commoditize the engine. For that reason they use the Apache Software License. So far several companies are backing that project. The "business model" is somewhat similar to that used by OpenStack.
It makes sense to have one BPMN 2.0 engine which is used and can be used by everybody. This does include jBoss (but I doubt that they will switch soon).
