underlying TCP connection. </p>
+
+<p>ActiveMQ implements this heart beating functionality, however before 
<b>5.9.0</b>, the heart-beat timeouts were strict; i.e., the were enforced 
without any kind of grace period.</p>
+
+<p>The STOMP spec does does state that the client/receiver should be tolerant 
of timing inaccuracies, so in version <b>5.9.0</b> we've added the following 
parameter:</p>

heart beats from the server.</p>

 <h3><a shape="rect" name="Stomp-WorkingwithDestinationswithStomp"></a>Working 
with Destinations with Stomp</h3>
 
 <p>Note that the prefix in stomp <b>/queue/</b> or <b>/topic/</b> is removed 
from the string before passing it to ActiveMQ as a JMS destination. Also note 
that the default separator in MOM systems is . (DOT). So <b>FOO.BAR</b> is the 
normal syntax of a MOM queue - the Stomp equivalent would be 
<b>/queue/FOO.BAR</b></p>
