My solution is to use Groovy wherever possible. It has a superb syntax, very low learning curve and compiles into JVM bytecode. There is no issue with getters and setters in Groovy - you just define the fields, which Groovy calls properties and defines implicit getters and setters.

If not for the main application code, I would definitely use Groovy for unit testing in combination with Spock Framework. You just have to try it once to realise what you've been missing all these years with JUnit.
