 * <li><code>Message</code> which doesn't have a body</li>
 * <li><code>TextMessage</code> with a <code>String</code> as body</li>
 * <li><code>ObjectMessage</code> with any <code>Object</code> as body</li>
 * <li><code>BytesMessage</code> with a body made of <code>bytes</code></li>
 * <li><code>MapMessage</code> with name-value pairs of Java primitives in its body</li>
 * <li><code>StreamMessage</code> with a stream of Java primitives as body</li>
 * </ol>
