Could somebody please tell as why is the above exception thrown and what should be done to resolve it struck with this for the past two days
Thank you in advance.

The payload you're trying to send to Rabbit looks quite complex (sfdc BatchInfo object). How do you except it to be readable for the queue consumer? I think that, for some reason, the message transformers involved in transforming this payload to a byte array suited for AMQP transport fails and you end up trying to send the groovy generated Map with an sfdc BatchInfo object as is to the AMQP client lib.
You should convert the map with contents to a string before sending it to Rabbit. Something like this (call toString on the BatchInfo object and then convert the map to JSON):
