Spring JmsTemplate & WebSphere MQ - ignoring RECEIVE_TIMEOUT_NO_WAIT

I am using Spring JmsTemplate and WebSphere MQ (inside WebSphere App Server).

I create the JmsTemplate instance as follows:

def templateFor(managerJndiName: String) = {
  val connectionFactory = context.lookup(managerJndiName).asInstanceOf[QueueConnectionFactory]
  val jmsTemplate = new JmsTemplate(connectionFactory)
  jmsTemplate.setReceiveTimeout(JmsTemplate.RECEIVE_TIMEOUT_NO_WAIT)
  jmsTemplate
}

Note, I set the timeout to be no_wait (-1). However, the thread still blocks.

What have I missed?

Because of the hack outlined in the comments of this question I thought I was using Spring 3, but I was using Spring 1. Looking at the code, Spring 1 does not support RECEIVE_TIMEOUT_NO_WAIT
