Description

Consider the following:

trait T {
  String string = 'value'
}

class C implements T {
  void meth() {
    println T.super.string
  }
}

new C().meth()

Executing this script results in "MissingProipertyException: No such property: super for class: T". The property can be read using "string", "this.string", "getString()", "this.getString()" and "T.super.getString()". And the property can be written using property notation, setter call, as well as "T.super.string = 'whatever'".

org.codehaus.groovy.transform.trait.SuperCallTraitTransformer lacks a transformation for property read access.
