Since I develop 99% on Java I would recommend anything along the lines of Spring Boot, Dropwizard or Wildfly Swarm. With Dropwizard I can't say much since I only played with it a little, on the other hand having developed projects with Spring Boot and Swarm I can say both do the job really well, both seem pretty much future proof (even though many claim JEE is dead).

Personally I would go with Swarm since I feel there is less work configuring it. With the added advantage of being used to develop in JEE Environments.
