Looking for solution to stop the task chain and not trigger onFailure or recover

Nobody has claimed this yet.

Is there a way to pause the task sequence, check condition and cancel out the sequence.

```
Task t1 = Task.value(orderData);

Task t2 = t1.andThen( d -> d.setCurrency(Optional.of("dollars")));

Task t3 = t2.andThen( d -> {
if(d.getCurrency().equals("dollars")){
System.out.println("The verification is not passed throw error");
//// This is the part doesnt work as what I think it is. Is there a way to stop the process fro the rest of the task and not trigger the onFailure in temp ??
t2.cancel(new OrderDatagramValidationException.Item.ExistsException(1,"abc",1));
}
});

Task temp = t3.andThen( t -> {
throw new Exception();
}).onFailure( t->{
throw new Exception();
});
```

Start with the Task.andThen, cancel, and onFailure calls shown in the issue and trace how cancellation and failure propagation are handled. Determine the supported behavior for stopping the sequence without invoking onFailure, and define completion as an implemented or documented way to achieve that behavior.
