BUG! exception in phase 'semantic analysis'... object is not an instance of declaring class...

[GoogleCodeExporter]

I'm getting this error for a trivial test:

Error Compilation error compiling [unit] tests: BUG! exception in phase 
'semantic analysis' in source unit 
'/vagrant/myapp/test/unit/myapp/SomethingSpec.groovy' object is not an instance 
of declaring class...

CODE:

package myapp

import grails.test.mixin.TestFor
import spock.lang.Specification

/**
 * See the API for {@link grails.test.mixin.domain.DomainClassUnitTestMixin} for usage instructions
 */
@TestFor(Something)
class SomethingSpec extends Specification {

    def setup() {
    }

    def cleanup() {
    }

    void "test something"() {
        expect:
        false
    }
}

ISSUE:

grails> test-app :spock
| Compiling 1 source files.
| Error Compilation error compiling [unit] tests: BUG! exception in phase 
'semantic analysis' in source unit 
'/vagrant/myapp/test/unit/myapp/SomethingSpec.groovy' object is not an instance

## What version of Spock and Groovy are you using?

Spock 0.7 and Groovy Version: 2.1.6 JVM: 1.6.0_27

Why in the name of the goats this test fails?!

Thanks in advance!

To determine what's causing this, we'll need at least the full stack trace, or 
better, a self-contained reproducible example. What's your exact spock-grails 
setup? Which versions of spock-grails and Grails are you using?

Now it magically works. I can't reproduce the error... =S
