Hi Alejandro,
Thank you for your reply. And I am glad to hear that we would have a plan to release jBPM 4.4. It is really a good news.
And Sebastian, Maciej and me are discussing about JBPM-2537, since it is a serious issue and will cause many changes in API, PVM and JPDL, we hope your could join our discussion. Thank you very much.
