Exception in when training set numlasses != test set numClasses

[GoogleCodeExporter]

Hope I'm not missing something basic.

What steps will reproduce the problem?
1. //Create a test set with a different number of classes as a training set
2. cls.buildClassifier(trainData);
3. Evaluation eval = new Evaluation(trainData);
4. eval.evaluateModel(cls, testData);

What is the expected output? What do you see instead?

Expected to complete evaluation successfully uith no output.

Instead, step 4 gives exception:
