Hi MaGuoWei, this is not a problem. If you look at the implementation of SlotAllocationFuture.setFutureAction, you’ll see that the method is synchronized on a lock which is also used to complete the future. Furthermore, you’ll see that the slot variable is checked upon setting an action and if it’s set the action will immediately be executed. Thus, if in between calls 1 and 2 the future was completed, then the slot variable would be set and thus also the action would be executed.
