RandomRBFGeneratorEvents problem

Version: 2012.09-SNAPSHOT

RandomRBFGeneratorEvents generates Instance objects correctly. The problem 
occurs when they are generated via noise. In that case 
weka.core.Instance.toString() throws exception, which is annoying because is 
not possible to use WriteStreamToARFFFile for example.

Here is an example:

import moa.streams.clustering.RandomRBFGeneratorEvents;
import weka.core.Instance;

public class InstanceGenerator {

    private RandomRBFGeneratorEvents randomRBFGeneratorEvents;

    public InstanceGenerator() {
        randomRBFGeneratorEvents = new RandomRBFGeneratorEvents();
        //randomRBFGeneratorEvents.noiseLevelOption.setValue(0);
        randomRBFGeneratorEvents.prepareForUse();
    }

    public Instance next() {
        return randomRBFGeneratorEvents.nextInstance();
    }

    public static void main(String[] args) {
        InstanceGenerator generator = new InstanceGenerator();

        for (int i = 0; i < 10; i++) {
            Instance instance = generator.next();
            System.out.println(instance.toString());
        }
    }

}
