If I recall correctly a singleton is a class that is available across the entire jvm, so if you intend it to handle all messages from lots of queues, I'd think it might quickly become a bottleneck for messaging. No expert in this but, from an integration perspective it would be more scalable and better from the perspective of different services stopping and starting for various reasons to be individually controllable like you can in most IE platforms. Don't know what your platform is or anything though.

Do not click links or open attachments unless you recognise the sender and know the content is safe. I have a follow-up question. The documentation says that HapiContext is not intended to be a singleton. Should it be fine to create one HapiContext in the singleton that I create to handle the incoming messages from my queue? It seems very inefficient to recreate the objects I need to send each message.
