Rajib Rashid commented on AMQ-3906:
-----------------------------------

Hi Gary, can you share how close you are to officially releasing 5.8? We don't mind using
a snapshot release as long as it is stable for production use. But this particular issue has
been caused some major headaches and we would like to make one big push to update all the
deployments. Thanks
