Descriptor Extractor causes errors

edit

i wrote the below code to do features matching for list of Mat objects, the problem is at run time i receive the below posted errors, as far as i understood it, i checked the extenstion and the size of the used image and they are .jpg and 538 * 522 except one image is 538 * 520

is the image with different size might cause such error? please help me to fix this issue.

Code:

  public static void main(String[] args) {
    loadOpenCVLib();
                                    /*Step_1: Feature Detection*/
    initFeatureDetector();
                                    /*Step_2: Descriptor Extractor*/
    initDescriptorExtractor();
}

private static void initDescriptorExtractor() {
    // TODO Auto-generated method stub
    descriptorsList = new ArrayList<Mat>();

    descriptorsList.add(new Mat());
    descriptorsList.add(new Mat());
    descriptorsList.add(new Mat());

    DescriptorExtractor descripExtractor = 
    DescriptorExtractor.create(DescriptorExtractor.SIFT);
    descripExtractor.compute(matList, keyPointsList, descriptorsList);
    //descripExtractor.write(fileName) test this method
    //descripExtractor.read(fileName)
}

private static void initFeatureDetector() {
    // TODO Auto-generated method stub
    matList = new ArrayList<Mat>();
    keyPointsList = new ArrayList<MatOfKeyPoint>();

    matList.add(path2Mat(path_jf00));
    matList.add(path2Mat(path_jf01));
    matList.add(path2Mat(path_jf02));

    keyPointsList.add(newMatKeyPoints());
    keyPointsList.add(newMatKeyPoints());
    keyPointsList.add(newMatKeyPoints());

    FeatureDetector featsDetect =    
    FeatureDetector.create(FeatureDetector.SURF);
    featsDetect.detect(matList, keyPointsList);
}

private static void loadOpenCVLib() {
    // TODO Auto-generated method stub
    System.loadLibrary(Core.NATIVE_LIBRARY_NAME);
}

private static Mat path2Mat(String path2File) {
    // TODO Auto-generated method stub
    return Highgui.imread(path2File);
}

private static MatOfKeyPoint newMatKeyPoints() {
    return new MatOfKeyPoint();
}

}
