the class Hessian2PersonOkTest method test_doubleArray_withType.

@Test
public void test_doubleArray_withType() throws Exception {
    double[] data = new double[] { 37D, -3.14D, 123456.7D };
    ObjectOutput objectOutput = serialization.serialize(url, byteArrayOutputStream);

    objectOutput.flushBuffer();
    ByteArrayInputStream byteArrayInputStream = new ByteArrayInputStream(byteArrayOutputStream.toByteArray());
    ObjectInput deserialize = serialization.deserialize(url, byteArrayInputStream);
    assertArrayEquals(data, (double[]) deserialize.readObject(double[].class), 0.0001);

// NOTE: Hessian2 throws ArrayIndexOutOfBoundsException instead of IOException, let's live with this.
