Right now, if tasked with building another service of the same type as the one I am currently creating (kind of a CRM integrated with various 3-rd party payments and messaging) I'd use the most recent version of my current stack. My current stack is JavaEE on TomEE. I'd probably happily sacrifice verified stack compliance for the latest TomEE 7 milestone build as I understand the verification issue is just Oracle being Oracle again, throwing a wrench in the gears just because 'why not'? Or rather to see if they can somehow extort some money from an open source project. </rant>
