    Just a note: `error` could be declared as a plain field (avoiding expensive full barriers
due to the volatile store of it).
    To allow atomic write/read of it can be used the acquire/release semantic provided by
the Java Memory Model ie `STATE_FIELD_UPDATER.lazySet(this, FAILURE)` will store-release anything
written before it (error = result) while `isComplete` (that contains a volatile load of `state`)
is load-acquiring anything store-released by `state` (the value of `error`).
