Arjan Seijkens created METAMODEL-1213:
-----------------------------------------

             Summary: Reading from CSV in a multi-threaded manner can corrupt results
                 Key: METAMODEL-1213
                 URL: https://issues.apache.org/jira/browse/METAMODEL-1213
             Project: Apache MetaModel
          Issue Type: Bug
            Reporter: Arjan Seijkens


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.
