[rabbitmq-discuss] RabbitMQ queue durability question

Here's your problem. RabbitMQ Grails plugin uses two different constructors to
create a Queue instance (that comes from Spring-AMQP, as far as I can see):

https://github.com/grails-plugins/grails-rabbitmq/blob/master/src/groovy/org/grails/rabbitmq/RabbitQueueBuilder.groovy#L30

Now look at the single argument constructor in org.spring.amqp.core.Queue:
http://static.springsource.org/spring-amqp/api/org/springframework/amqp/core/Queue.html

It says "The queue is durable, non-exclusive and non auto-delete".

So looks like *some* of the time your Grails app was started without a config param that
led the Grails plugin to create a durable exchange.
