I added an earlier patch in this chain, https://reviews.apache.org/r/63917/.

I agree that we should probably pull changes to the total resources out of 
`addOfferOperation` (mainly since the updates to `total` and e.g., `operations` 
are coupled, but the method works on smaller granularity leading to a mismatch).

This is not strictly required for this patch chain and I would suggest cleaning 
this up in a later patch.
