I'm more than willing to take this task on, but I'll need some pointers on where the cause of the problem lies and how to tackle it. This is now a critical issue for my project, so any help at all would be greatly appreciated.

In addition, I think a related problem can be observed if, for example, a seam timer (using ejb3 timer implementation) causes a process instance to create a jbpm timer:
