> Spring for JVM? [...] I can recommend Grails > nobody forces you to use Java for Spring, I prefer Groovy Recently the Groovy/Grails sponsor VMWare split them off from Spring and retrenched all the developers working on them, while keeping their ownership of Spring. The only reason I can think of is they didn't want Spring dependent on Groovy or Grails in any way, so if you use either of them with Spring, you might have incompatibility problems in future.
