/**
 * Tests read/write of Integer via native JavaleSerialization.
 * @throws Exception If fails.
 */
public void testIntJavaSerialization() throws Exception {
    HadoopSerialization ser = new HadoopSerializationWrapper(new JavaSerialization(), Integer.class);
    ByteArrayOutputStream buf = new ByteArrayOutputStream();
    DataOutput out = new DataOutputStream(buf);
    ser.write(out, 3);
    ser.write(out, -5);
    ser.close();
    DataInput in = new DataInputStream(new ByteArrayInputStream(buf.toByteArray()));
    assertEquals(3, ((Integer) ser.read(in, null)).intValue());
