Only "gini" and "entropy" (in lower case) are accepted

> I saved a CrossValidatorModel with a decision tree and a random forest. I use Paramgrid to test "gini" and "entropy" impurity. CrossValidatorModel are not able to load the saved model, when impurity are written not in lowercase. I obtain an error from Spark "impurity Gini (Entropy) not recognized.
