> 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.
