MLP call invalid in Clojure API

the code fails with

Cannot invoke "clojure.lang.IFn.invoke(Object, Object, Object, Object)" because "null" is null

The following does work:

(let [net (smile.classification.MLP. builders)]
   (.setLearningRate net (smile.math.TimeFunction/linear 0.2 1000 0.1))
   (.setMomentum net (TimeFunction/constant 0.2))
   (.setWeightDecay net 0.1)
   (dotimes [i 10] (.update net x y))
   )

Very likely the

  ([x y builders] (mlp x y builders 10 0.1 0.0 0.0))

will not work any more neither, as it needs now TimeFunctions for the MLP params momentum and leariningRate
