Which scripting language should I sue

Scala is particularly attractive to Java developers. Per its website: "Scala... is both object-oriented (think inheritance, methods, ...) and functional (think closures). It blends a number of modern language features, while maintaining close compatibility with Java."

Formally, Lua is "a powerful, fast, light-weight, embeddable scripting language. Lua combines simple procedural syntax with powerful data description constructs based on associative arrays and extensible semantics. Lua is dynamically typed, runs by interpreting bytecode for a register-based virtual machine and has automatic memory management with incremental garbage collection, making it ideal for configuration, scripting, and rapid prototyping."

Your company may be adopting the latest hardware, but can your software take advantage of its multithreading capabilities? You might want to look at Clojure, a dynamic programming language that targets the JVM. Explains its website, Clojure is "designed to be a general-purpose language, combining the approachability and interactive development of a scripting language with an efficient and robust infrastructure for multithreaded programming. Clojure is a compiled language—it compiles directly to JVM bytecode, yet remains completely dynamic. Every feature supported by Clojure is supported at runtime. Clojure provides easy access to the Java frameworks, with optional type hints and type inference, to ensure that calls to Java can avoid reflection."
