I feel like Scala is poised to become the successor to Java on the JVM. But migrating from large-team Java and Java EE presents many challenges. For instance, what to do to assure a comfortable level of stylistic uniformity throughout the codebase? What if your senior engineers want to use, say, scalaz, and you're worried that the mid- and junior-level developers on your team won't be able to understand it? Just which technologies should you choose, and how do you know they are robust and stable? I've created a Google+ group for Java EE expats (and their loved ones) to discuss issues like this. Please stop by and share your thoughts.
