A modern programming language that makes developers happier.

kotlinlang

hi, I posted this over the w-e but the room was pretty quiet then (serves me right!). I'm thinking of starting a new web app project in Kotlin (JSON web api back-end for a rich front-end). Any recommendations on the following that a) play well with Kotlin and b) are the current 'go-to' solutions is Java dev? (I have spent the last few years in the CLR): web framework, logging, DI (Kodein?), testing, mocking, and possibly ORM (Icicl, Jooq, requery)?
