    Description

      We have a problem in two places: 

      null nodes could be created here MeanDecisionTreeLeafBuilder.createLeafNode method in the row return aa != null ? new DecisionTreeLeafNode(aa[0]) : null;

      Probably, this situation is arising then the amount of features is smaller than maxDeep
