[scarbo87]

RabbitMqDelayPluginDelayStrategy: options x-delay must be header, not the property

#455

[makasim]

@scarbo87 Have you tested it? I am sure we've tested it and it worked

[scarbo87]

@makasim, your code works for RabbitmMQ version 3.6.6, but doesn't work for version 3.7.5.
Can I make a new RabbitMq375DelayPluginDelayStrategy?

@scarbo87 Is there a link I can read more about the change?

@scarbo87 that would be great

@makasim, can I update the docker rabbitmq image?

[makasim]

you could add another one with 3.7 version in it. and force 3.6 for current one.

@makasim, added RabbitMq375DelayPluginDelayStrategy

@scarbo87 I've updated rabbitmq image to 3.7 with a delay plugin and the current implementation of delay plugin works, at least tests are passing.
