If you expect the fork to behave as a multi-threaded parallel execution, then sorry.. that is not what jBPM is/does. If you want that, make the nodes in each leg of a fork async, but not the fork itself. According to the code, async on a node locks the currenttoken. Not strange then that in the join it cannot be reactivated. So try removing the async on both join and fork.
