> * In MessageDispatcher.castMessageXXX() and send(), we pass a Message as argument. Change this to only ship the byte[] buffer and options.
> ** This prevents a unicast RPC from having a message with a null dest, or a multicast RPC having a message with a non-null dest (JGRP-1617).
> * Sync and async calls
> ** If a unicast call is async, return null immediately after sending it
> *** In case of a callWithFuture() -> return a null future as well (not a {{NullFuture}}!)
> * If a multicast call is async, return null immediately (instead of an {{RspList}})
> *** In case of a callWithFuture -> return a null future (instead of a {{nullFuture}})
> * Investigate whether non-blocking RPCs need to create Request instances at all
> ** This prevents creation and population of the hashmap (for {{GroupRequest}})
> ** Async requests could be dispatched to {{RequestCorrelator}} directly
> * Return a {{CompletableFuture}} instead of a {{NotifyingFuture}}
> * Remove {{NotifyingFuture}} and {{FutureListener}}: requires changing {{ExecutionService}}
> ** Perhaps: https://github.com/wburns/infinispan/blob/ISPN-6074/core/src/main/java/org/infinispan/manager/ClusterExecutor.java
> * Replaced {{org.jgroups.TimeoutException}} with {{java.util.concurrent.TimeoutException}}
