Error in PoolingLayer constructor

[Aerocool]

Dear developer team,

I think your PoolingLayer constructor is having a bug in line 90.

public PoolingLayer(FeatureMapsLayer fromLayer, Dimension2D kernelDim, int numberOfMaps, NeuronProperties neuronProp) {
        this.kernel = this.kernel;

Instead it should be

this.kernel = new Kernel(kernelDim);

like in the constructor above.
I also suggest that one constructor calls the other one giving the default parameters for better maintenance. Something like:

public PoolingLayer(FeatureMapsLayer fromLayer, Dimension2D kernelDim) {
       int numberOfMaps = fromLayer.getNumberOfMaps();
       this (fromLayer, kernelDim, numberOfMaps, DEFAULT_NEURON_PROP);
    }

    public PoolingLayer(FeatureMapsLayer fromLayer, Dimension2D kernelDim, int numberOfMaps, NeuronProperties neuronProp) {
        this.kernel = new Kernel(kernelDim);
        Dimension2D fromDimension = fromLayer.getMapDimensions();
        int mapWidth = fromDimension.getWidth() / this.kernel.getWidth();
        int mapHeight = fromDimension.getHeight() / this.kernel.getHeight();
        this.mapDimensions = new Dimension2D(mapWidth, mapHeight);
        this.createFeatureMaps(numberOfMaps, this.mapDimensions, kernelDim, neuronProp);
    }
