> Re-use connections / sessions / consumers / producers. Probably the most common messaging
anti-pattern we see is users who create a new connection/session/producer for every message
they send or every message they consume. This is a poor use of resources. These objects take
time to create and may involve several network round trips. Always re-use them.
> Note that a JMS section needs to be "thread local". Rationals: the rollback operations
rolls back the entire session.
