> The only way to return a result from RegionObserver.preIncrement() is to use Result.readFields()
after serializing the correct result.
> This can be fixed either returning a Result object from that function or adding setters
to Result. Another option is to modify the parameters and receive a List<KeyValue> as
preGet() does.
