Just about any other OOP language. I don't find reflection itself to be particularly helpful, e.g., the only times I used it in Java were during low-level framework creation and code generation. Anything else is better handled via interfaces or similar functionality. But if I were forced to use the JVM (which is a nice platform) I'd tend towards Clojure (distinctly not OO). If OO was a strict requirement then Groovy or Scala. Java's OOP implementation, however, is fairly limited in scope, although Java 8 has somewhat alleviated my own particular pain points (e.g., lambdas).
