It seems that within my Junit test i can have non-fully contained fork/joins, and that provided i get the correct child token (and childs-child etc) to signal, then it works succesfully. Is there any documentation on how taskInstance signalling works? Since I think maybe the problem is more to do with the taskInstance signal, than the token signal.
