Cannot resolve symbol from where: section after instanceof

[GoogleCodeExporter]

I want to do something like this:    

@Unroll
def " should contain #clazz.getSimpleName() bean"() {
        given:
        builder.build()

        when:
        def component = builder.getContainerComponent(clazz)

        then:
        component instanceof clazz

        where:
        clazz << [Javers, EntityManager, TypeMapper, DiffFactory]
}

but in line 10 i have compilation problem. The IntelliJ tell's me that cannot 
resolve symbol clazz, but when i use Assertj and do something like this (in 
line 10):

assertThat(component) isInstanceOf(clazz)

it works ;)

I try in Intellij 12 and 13.
