    Description

      If the input file ends with comment lines, the parser runs into an endless loop. The example shows, that the CSV parser runs into an endless loop, if the input is one comment line. '#' is the comment character here:

      import org.apache.commons.csv.CSVStrategy;
      import org.apache.commons.csv.CSVParser;
      import java.io.StringReader;
      import java.io.IOException;
      
      public class TestCSV {
          public static void main(String [] args) throws IOException {
              CSVStrategy strategy=new CSVStrategy(',','"','#','\\',false,false,false,false);
              
              CSVParser parser = new CSVParser(new StringReader("# A, B\n"), strategy);
              
              System.out.println("Go into an endless loop...");
              String []line=parser.getLine();
          }
      }
