title: Message availability on JMS Topic once client acknowledges it?
body: <p>I have a simple scenario, where publisher(my java application) publish the
  message on topic. 50 clients have subscribed on  same JMS topic.As soon as message is published on topic, all the 50 subscriber will be notified
  .Say only one subscriber(0ut 0f 50) process the message  and send the acknowledgement
  after processing.(Once this client processing is done, i can see the message as consumed
  on apache MQ console. Otherwise if no client sends the acknowledgment after receiving the
  message i see the message as pending message). </p>
  
  <p>Now question is once any client sends the acknowledgment  and any
  new client subscribe on topic, will he be notified about the message ? or it works in a way where message has been
  consumed by any of the client (which internally means acknowledgment has been sent by any of the client), no  further notification will be
  sent to any new subscriber and message will be taken off from the Topic(This is the behaviuor i am experiencing  but looks like
  it should not work in this fashion as per as per Publish/subscribe model under <a href="http://en.wikipedia.org/wiki/Java_Message_Service" rel="nofollow">http://en.wikipedia.org/wiki/Java_Message_Service</a> )?</p>
