Of course patches for existing issues (or new ones) are very much appreciated. You can always come to talk to us on the #jbpm channel on codehaus, where most of us try to hang out. It is indeed true that the PVM could be leveraged to support multiple languages, and we're not planning to remove that. Our first focus will be on BPMN2 though, not on jPDL or BPMN. Regarding BPEL integration, I do agree that they could use some integration, as they are basically very similar. That's why we are planning to reuse as much of the components in the architecture as possible with the RiftSaw project. When you are talking about integration of BPEL and BPMN, I think there are various options, ranging from tool integration over API integration to running them on the same PVM, each having their own (dis)advantages. So it would be very useful if you could elaborate a little bit on this. Kris
