> The following block in Leader.getEpochToPropose:
> {noformat}
> if (lastAcceptedEpoch > epoch) {
> epoch = lastAcceptedEpoch+1;
> }
> {noformat}
> needs to be fixed, since it doesn't increment the epoch variable in the case
> epoch != -1 (initial value) and lastAcceptedEpoch is equal. The fix trivial
> and corresponds to changing > with >=.
