Can't find grails-gorm for Grails 2.1.1 anywhere

I am having problems running my Grails 2.1.1 app on JBoss 4.2.3 GA.

This time I am getting the exception below.

This line:
tells me that I am using the wrong version of grails-gorm.jar.

This it true, since the latest version I could find anywhere is 1.3.7.
However what I really need is a version compatible with Grails 2.1.1.
The one the contains a version of class HibernatePluginSupport that has the property onChange.

There are clues that this version exists somewhere...
http://grails.org/doc/latest/guide/GORM.html
http://grails.org/doc/latest/api/org....html#onChange
So, where can I get grails-gorm 2.1.1?
