> This is probably just a slice of GROOVY-1591, GROOVY-3010, GROOVY-3142, GROOVY-5438, et al. Adding {{super.}} qualifier causes strange behaviors. Please consider the following:
> {code:java}
> class Foo {
>   private String field = 'field'
>   private String method() { 'method' }
> }
> class Bar extends Foo {
>   def baz() {
>     field // MissingPropertyException: No such property: field for class: Bar
>     method() // MissingMethodException: No signature of method: Bar.method()
>     this.field // MissingPropertyException: No such property: field for class: Bar
>     this.method() // MissingMethodException: No signature of method: Bar.method()
>     // so far, so good -- although Groovy allows access to private fields and methods from outside of Bar and Foo
>     super.field // MissingMethodException: No signature of method: Bar.getField() -- that's strange
>     super.method() // returns "method" -- Why is this okay?
>     super.@field // MissingMethodException: No signature of method: Bar.getField() -- that's strange
>     super.&method // returns MethodClosure that throws NPE when called:
>     (super.&method)() // NullPointerException: Cannot invoke method call() on null object-- If super.method() works, why doesn't this?
>   }
> }
> {code}
