title: JMS AUTO_ACKNOWLEDGE when is it acknowledged?
body: <p>I have tried to google this, but have not been successful. If I am using <code>AUTO_ACKNOWLEDGE</code>, and I have a consumer client written in Java, when is the message acknowledged? I am using a <code>MessageListener</code> which contains an <code>onMessage</code> method. Is the acknowledgement sent back to the server before <code>onMessage</code> or after <code>onMessage</code> completes or at some other point? Thanks in advance for any help anyone is able to provide!</p>
