-----------------------------------------
[~Mmuzaf],
Thanks for spotting this!
It seems we missed a case when lastEntry may be empty. We may choose here from
two options:
* Check if histMap is empty inside *onCheckpointFinished*. If it is just don't
log anything (it was the very first checkpoint).
* Check in caller that there is no history, calculate necessary index in caller
and pass it to *onCheckpointFinished* to prepare correct log message.
Could you please file a ticket for this and prepare a pull request?
