Thanks for your reply. Still I keep asking myself; if the docs mention concurrency amongst processes and it is possible to use forks (like forEachForkActionHandler), which look like they are based on the same principle (of using concurrency/threads), then why not having the option of creating threaded forks/transitions? I mean, if a fork splits in three transition/nodes that can be executed parallel and join into one node finally, then that would be quit a nice feature if it were implemented in jBPM, not?
