Using andThen on the completes returned from Actor.completes() throws UnsupportedOperationException exception #69

Closed buritos closed 4 years ago

buritos commented 4 years ago

...
public Completes<Integer> boom() {
  return completes().with(1).andThen(one -> one + 1);
}
...

When boom is called on the actor proxy created via World.actorFor it throws:

java.lang.UnsupportedOperationException: null
    at io.vlingo.actors.ResultReturns.andThen(ResultReturns.java:38)

I was expecting a successful Completes with the Integer value 2 inside.

@buritos My feedback is in Slack. If you want to condense any of that and put it here for later reference that's fine.

This was fixed by the following and some redesign.
