    Description

      The following combination is needed:

      • an interface IX with at least one getter/setter pair
      • a trait IY extending IX
      • a class K implementing IX
      • a jittable constraint on IX

      The constraint is first triggered by an "instance" of IY,
      but jitted by an instance of K.
      The condition analyzer assumes that IY is the natural
      domain of the constratint, rather than IX. The jitted
      constraint will then try to cast K to IY, resulting in
      a disruptive CCE
