> Depending on the cache level, the JMSConnectionFactory stores a "shared" 
> session and/or message producer. These objects are used by the JMSSender (via 
> JMSMessageSender). Since sessions and producers are not thread safe, this 
> will lead to concurrency issues. Note that initially the JMSListener used a 
> similar pattern. This has been corrected [1], but the issue has never been 
> addressed for the JMSSender. The concept of "shared" session/producer should 
> be eliminated altogether from JMSConnectionFactory.
