Description

Presently, you can ask the LogReader for 0 records via the method #readBulk(int). That's pretty silly.

We should validate that the user is strictly asking for one or more records from the LogReader.

Same goes for the LogReader#readBulk(List) variant – we should require that the provided list be at least size one.
