I think problem with CSVUtils.parseline is, that it parses only specific quotes. But we have here the possibility of getting double and single quotes, because there is nothing defined at http://www.cs.waikato.ac.nz/ml/weka/arff.html
But I could not find CSVUtils in repository.

> If the nominal values contain a value like integer, real or string it will be misinterpreted as such instead of nominal.
