> When you access a CSV file using a _SingleLineCsvDataSet_ and read from it in parallel manner in a multi-threaded environment, it is possible you get corrupted results for values in the CSV file, typically you'll sometimes get a _"_  (the double quote character) for empty fields.
> I will add a link to a branch demonstrating the issue through a unit test here.
