title: Apache common CSVParser/CSVRecord to return null for empty fields
body: <p>all</p>
  
  <p>I have a question for Apache common CSVParser/CSVRecord. Take a look at the CSV file below:</p>
  
  <pre><code>Header1,Header2,Header3
  "",,"L1C3"
  </code></pre>
  
  <p>CSVParser/CSVRecord is returning "" for the first two columns. In my case I want to distinguish empty string("") and null values. Is there a configuration I could set to let CSVParser to return null for the second column?</p>
  
  <p>Thank you.</p>
