The more I read, the more I think we have to do an evaluation of options 
here.  See, e.g. https://jira.spring.io/browse/AMQP-662

Note for Spring users: Spring-jms supports AMQP 1.0, while Spring-amqp 
supports AMQP 0.9.  See stackoverflow message from last week:   
https://stackoverflow.com/questions/45461589/can-spring-amqp-connect-and-process-messages-from-amqp1-0-brokers/45462037#45462037

RabbitMQ does have a plug-in for AMQP 1.0 
(https://github.com/rabbitmq/rabbitmq-amqp1.0/blob/rabbitmq_v3_6_10/README.md 
).  Chris, what do you think? It would be much better to be on AMQP 1.0 if 
feasible.

Subject: [grouper-users] Re: [tier-api] grouper rabbitmq messaging

The reason the product keeps being specified is because the Wiki page for 
'Grouper Messaging with RabbitMQ' [1] talks about an integration which uses 
amqp-client-4.0.2.jar by RabbitMQ [2], which implements the AMQP 0.9.1 
protocol [3]. Although RabbitMQ promulgated the AMQP spec first, the later 
version AMQP 1.0 is not compatible, and that's the version that has seen 
adoption in other messaging products. Therefore, this Grouper integration is 
indeed compatible with RabbitMQ, but essentially no other messaging product, 
making the distinction important.

I am excited about this capability.  From the conversations I have 
participated this work was supposed to be about supporting the AMQP protocol 
and not specifying the product - RabbitMQ.  AMQP is supported by nearly all 
the popular messaging products.  I think it would be wise to go with AMQP 
support for Grouper and not specify the product.
