Essentially, Java is already run like containers, that container being an application server of some sort. Very rarely is Java software really dependent on specific packages being installed or even which operation system aside from a particular Java VM. When you add another container layer you generally are just adding more overhead and further you have issues with correctly setting some tunable parameters like heap sizes vs container memory sizes, etc. It works, it just isn't very ideal.

Thanks for your reply spullara. We might be one of those rare cases where we do need different packages and libraries for each applications. It's the pain that we have to suffer having to maintain several "legacy" apps.

Regarding your view on an app server being a container of some sort, I do agree. We are actually starting to develop apps to be run using embeded app servers (with Spring Boot), as it fits better when running apps using docker.

Makes sense. I've been recommending Dropwizard for years for similar reasons.
