No, it isn't. I was a Scala enthusiast but experience has taught me to like Java and its maturity and dislike Scala's unstable complexity (maybe it's more stable now than back when I was onboard) but the language by design embraces abstraction building that is nice-looking superficially but deeply hard-to-understand when different features interplay, which also makes the tooling harder to get right.

Also, Spring is not that bad, though sometimes I have hard time to understand some of the initialization/runtime problems. Hibernate and JBoss I rather skip, and use Tomcat and Dalesbred for relational data access.
