title: Which JMS implementation do you use?
body: <p>We are using <a href="http://activemq.apache.org/" rel="noreferrer">ActiveMQ 5.2</a> as our implementation of choice and we picked it a while ago.  It performs well enough for our use right now.  Since its been a while, I was wondering what other Java Message Service implementations are in use and why?  Surely there are more than a few.</p>
