Despite nemoniac's post, I think you're on the right track with Java. There's plenty of Java work out there, and modern Java is a better than average language to work with.

Given that you've done some functional programming, you might also want to investigate Scala. There's probably not too much Scala work out there right now, but you might be able to evangelize it for some appropriate workloads once you're doing Java development. It completely interoperates with Java (it runs on the JVM also). I think it's one of the best designed modern languages.
