Project Lombok modifies your development environment to enable extra java language features. Right now lombok can inject itself into both javac and eclipse and offers both Automatic Resource Management and generating getters, setters, equals, hashCode, and toString, and a couple of other features. A screencast takes you through how it works and even shows you how to install it, and clocks in at less than 4 minutes. It's open source (MIT license).
Very interesting, there's obviously a lot of demand for other enhancements to the language, do you see development of features such as closures in the future?
