[infinispan-dev] NotifyingFuture vs Deferred

Deferred is not different from NotifyingFuture fundamentally. The only difference is how it handles an exceptional case and callbacks can return another Deffered, which makes chained asynchronous operations possible. This difference opens a lot of possibilities for performing a series of asynchronous operations. It can be compared to dynamic construction of interceptor chains. So, I'd like to propose to replacing the current NotifyingFuture implementation with Deferred. I think the name 'Deferred' is somewhat less intuitive, so retaining the name might be a good idea.
