[Raghav Babu]

I am getting an ExecutionException while i do CompletableFuture.get()... I submitted a write which is implementing Command to CopycatClient and trying to get back CallableFuture.. But  am getting an exception.

Exception stack flow is..

I responded to this in Copycat/Atomix chat. We should discuss it there if possible.
