 * Make sure that permuted arrays do not hash to the same value.
 */
public void testPermutedArrayHash() {
    double[] original = new double[10];
    double[] permuted = new double[10];
    RandomDataImpl random = new RandomDataImpl();

    // Generate 10 distinct random values
    for (int i = 0; i < 10; i++) {
        original[i] = random.nextUniform(i + 0.5, i + 0.75);
    }

    // Generate a random permutation, making sure it is not the identity
