Grails domain classes not recognized

Grails allows to declare the domain classes in Java which allows using those entity classes with Java code.
See section 16.2 of [http://grails.org/doc/latest/guide/hibernate.html](http://grails.org/doc/latest/guide/hibernate.html)

When doing so, IntelliJ does not recognize those classes as GORM domain classes.
For example, when you type "employee.save()" the save() method is underlined.
Also the method completion for GORM API does not work (especially for the dynamic finders).
When typing Employee.findAllBy| followed by Ctrl+Space does not show the methods available.

Start by reproducing the issue with a Grails domain class declared in Java. Check why IntelliJ does not recognize employee.save() or offer completion for Employee.findAllBy, then verify that GORM methods and dynamic finders are recognized and suggested.
