>             Project: Commons CSV
>          Issue Type: Bug

>
> if you call CSVParser.getLine() or nextToken() with a line that is a comment as defined by the CSVStrategy but it doesn't contain the delimiter character, the call hangs in an infinite loop
> This code will hang:
> {code}
>         parser = new CSVParser(new StringReader("# abc\n"), new CSVStrategy('\t', '\'', '#'));
>         tokens = parser.getLine();
> {code}
> However, if you insert a delimiter char into the incoming string, it'll come through and return an empty string as a result:
> {code}
>         CSVParser parser = new CSVParser(new StringReader("#\tabc"), new CSVStrategy('\t', '\'', '#'));
>         String[] tokens = parser.getLine();
>         System.out.println("result: "+Arrays.toString(tokens));
> {code}
> It gets stuck in an infinite loop in CSVParser.nextToken() in the loop around line 347
