Spring JMS Session Issue When Using Open MQ - spring

Question

I'm using spring-jms-3.0.6.RELEASE and open MQ. Any ideas on why the below exception would be raise?

According to the ConnectionAdapter source code and this archive thread on OpenMQ mailing list, either Spring or your code itself creates more than one session on a single JMS Connection.
This OpenMQ behavior (raise an error) can be disabled by setting the system property imq.jmsra.inACC to false but it is not satisfying.
Without transaction manager, Spring uses org.springframework.jms.connection.SingleConnectionFactory to share a single connection for multiple consumers.
You should set DefaultMessageListenerContainer cacheLevelName property to CACHE_NONE so that each consumer thread gets its own session on a single connection.
