JMS Error - JNDI lookup of name QueueConnectionFactory returned a x.y.z while a interface javax.jms.ConnectionFactory was expected

If you happen to experience this error when working with any WSO2 product you can resolve it by removing the geronimo-jms_1.1_spec-1.1.0.VERSION.jar from $CARBON_HOME/repository/components/lib. This occurs due the availability of multiple implementation of javax.jms.* in the system classpath. You'll notice the following familiar stack trace.
