Groovy is a dynamic programming language for the JVM that is a near super-set of Java. Much Java syntax is valid Groovy syntax, however, Groovy adds powerful meta-programming features and Groovy on GAE will bring these meta-programming features to App Engine development. Groovy got special attention from the SpringSource Groovy team and the Google App Engine Java team and it was this collaboration that helped create the changes that were the big secret in the recent Groovy release of 1.6.1. The Groovy Developer community is very excited to see this level of collaboration between the Groovy team and Google!
