The problem is the same as with CRs 6773022, 6773586.

Methods:
 SampleModel.getSamples(int x, int y, int w, int h, int b, float fArray[], DataBuffer data)
 SampleModel.getSamples(int x, int y, int w, int h, int b, double dArray[], DataBuffer data)

/**
  * @throws ArrayIndexOutOfBoundsException if the coordinates or
  * the band index are not in bounds, or if fArray is too small to
  * hold the output.
  */

Extract from the tests:
-----
import java.awt.image.*;

public class Sample {

    public static void main(String[] args) {
        int defaultWidth = 6;
        int defaultHeight = 4;
        SampleModel model =
                Raster.createBandedRaster(DataBuffer.TYPE_INT, defaultWidth,
                        defaultHeight, 4, null).getSampleModel();
        DataBuffer data = model.createDataBuffer();
        int numElements = defaultWidth * defaultHeight * model.getNumBands();
        int[] a = new int[numElements];
        for (int j = 0; j < numElements; j++) {
            a[j] = j;
        }
        model.setPixels(0, 0, defaultWidth, defaultHeight, a, data);
        float[] fArray = new float[defaultWidth * defaultHeight * model.getNumBands()];
        double[] dArray = new double[defaultWidth * defaultHeight * model.getNumBands()];
        model.getSamples(Integer.MAX_VALUE, 0, 1, 1, 0, fArray, data);
        model.getSamples(0, Integer.MAX_VALUE, 1, 1, 0, fArray, data);

        model.getSamples(Integer.MAX_VALUE, 0, 1, 1, 0, dArray, data);
        model.getSamples(0, Integer.MAX_VALUE, 1, 1, 0, dArray, data);
    }
