      There seems to be some bug in class Instances. if an object of class Instances \
is created directly by new Instance(...), all its member functions work well. While \
created indirectly, like by Instances.trainCV(...), some of its member functions fail \
to work. The following program prints the result of Instances.trainCV(...).toString() \
with a strange number. <p>    <p>public class Test {<p>   public static void \
main(String[] ops) {<p>     try {<p>       Instances insts = new Instances(new \
FileReader("data/iris.arff"));<p>       System.out.println(insts.trainCV(3, 1));<p>   \
} catch (Exception e) {<p>       e.printStackTrace();<p>     }<p>   }<p>}  \
