issue can be solved different ways:
{quote}
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.{quote}
