It is common to create many sessions from a single connection (this is
what the ActiveMQ pool and the Spring CachingConnectionFactory both
do). Most JMS brokers are very good with this model. Each consumer
should create its own sessions from a given connection and sessions
should not be shared among consumers.

Correct, sessions should be exclusive to a specific consumer and
should not be shared at all.
