I am the maintainer of the Eclipse BPMN2 project. For the next major release, we plan to remove the JBPM components of Eclipse-BPMN2. The JBPM Extension has been part of the code base of Eclipse BPMN since the beginning. In order to improve the project structure of Eclipse BPMN2, we want to outsource this extension analogous to the BPMN2 extension Imixs-BPMN. I can support your project by moving the extension into a separate pure extension project if needed. 

What do you think about this change? I am not sure if the JBPM BPMN designer is directly affected by our change? 

Can you please share your opinion.
