Hello Marshall,
                     Thank you for the suggestion! This works for us! As
per your suggestion, we have now created an Aggregate Analysis Engine that
contains CAS Multiplier (Splitter), our original aggregate engine and CAS
Merger (to merge the results into one CAS at the end).

But the final merged CAS contains the child CAS'es (created in the
splitter) and the parent CAS as well. Is this expected? Any idea why?

We used CAS splitter and merger for a synchronous UIMA pipeline as well.
That does not give us the parent CAS in the final result (Merged CAS). Why
the difference?

Harshal
