Results show that Groovy is very slow in comparison to the pure Java and the Scala scripting language. This could be a serious reason to be worried when your application created with Grails or RoR goes in production...
So, why don't you use a real Java RAD tool like Roma Meta Framework? :-)
You can develop shortly without using a scripting language with the benefits of great refactoring support (Eclipse, Netbeans and IntelliJ are master on it) and performance and scalability!

Furthermore pre-packaged modules such as ADMIN, USERS, MESSAGING and SCHEDULER-QUARTZ needed to self-execute the enhancement in order to put persistence capable classes inside the JAR. This was a mess if you needed to change the ORM binding since anything resided inside the JAR.
I have to check yet if run-time changes to the entity POJOs are auto-enhanced at the fly... If works the productivity would be speedup over and over again.
Thanks to Andy Jefferson of DataNucleus team in supporting my crazy requestes :-) The work tomorrow will be in changing all the wizards to support the new configuration. In few words the change consist in:
- Let to the PersistenceAspect to invoke the Enhancer at startup
- Create the file persistence.xml inside the src/META-INF folder.
