Any word on when the next version would be out etc?
Currently, we are focusing on integrating jBPM BPEL with the new SOAP stack developed by the JBoss Web Services team. Once this integration is complete, our BPEL runtime will enjoy better performance, proper support for document/literal endpoints and WS-Addressing support.
Compensation and fault handling are also on their way, but we won't be able to deliver them earlier than beta 3. In fact, fault and compensation handlers are already parsed and the graph elements created for them, it is just a matter of sorting things out. If you are interested in contributing, I could point you to the right places :-)
