Breiman example issues

[Roshan A. Punnoose]

Hi,

I am trying to run the Breiman decision tree at 
http://cwiki.apache.org/MAHOUT/breiman-example.html with the glass data, but I 
keep getting this error when I actually run the Breiman example:

Exception in thread "main" java.lang.IllegalArgumentException: labels.length != 
predictions.length

I believe I’m at the latest trunk since a week ago.
