'this' in static context not treated as class by @CompileStatic

This Groovy script fails to compile:

@groovy.transform.CompileStatic
class MyClass {
    static void main(String[] args) {
        println "Class loader: ${this.classLoader}"
    }
}

MyClass.main([] as String[])

It complains that MyClass doesn't have a classLoader property. It seems that the static type checker does not treat this correctly in the context of a static method/property/initialiser.
