Since you have a transition from task3 to the join, it is in the incoming transitions and the join expects an incomming token/execution. It cannot easily decide there will not be a token comming from task3. Two things come to mind: - implement your own join node - use the n-out-of-m configuration (multiplicity attribute, see docs) View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4266876#...
