IDEA 9 - 95.24 does not run Grails 1.3.0.RC1 unit tests correctly

I've just upgraded a project to Grails 1.3.RC1.

My Grails unit tests are defined as usual like the following:

class ApplicationServiceTests extends GrailsUnitTestCase {
     protected void setUp() {...}
     protected void tearDown() { ...}
     void testLoadApplication () { ... }
}

If I run the tests from the command line with:

> grails test-app unit:

I defined a Grails run configuration for the module with command line "test-app unit:", But when I run it, IDEA steps in some how and fails to run the tests.
