Jython's been around since 1997-ish but isn't used much, nor is JRuby. As for Groovy, I recently looked into its apparent popularity at #17 on the TIOBE ranking and found Baidu was giving a result 12 times too high and Yahoo a result 20 times too high, both of which would skew the ranking. Groovy's real ranking is somewhere below that of #50 ranked Clojure.
