使用Spock存根@Immutable groovy类

Question

For instance I have a class

@Immutable
class User {
    String id
}

and I want to stub it in the way I used to stub java classes

def "should stub class"() {
    given:
    def validator = new BitSolutionValidator(eventBus)
    def student = GroovyStub(User)

    when:
    validator.onStudentHandedOverBitSolution(new StudentHandedOverBitSolutionEvent(
            student, GroovyStub(BitTask), GroovyStub(BitSolution)))

    then:
    student.id >> STUDENT_ID
}

But when the code executed I noticed student.id returned null. Is there a way to stub @Immutable groovy classes using Spock or I have to use metaClass?

我已经将grails版本升级到2.4.3，问题已解决。
