      Description

      You get a StackOverflow Exception when running following code:

      A.groovy
      abstract class A {
          A attach(){
              System.out.println( "A does something else");
              return this;
          }
      }
      
      B.groovy
      class B extends A {
          @Override
          B attach(){
              System.out.println("B does something else");
              return (B) super.attach();
          }
      }
      
      C.groovy
      class C extends B {
          @Override
          C attach(){
              System.out.println("C does something else");
              return (C) super.attach();
          }
      }
      
      Test.groovy
      C c = new C(); c.attach();
      

      This bug only occurs when the depth of the class hierarchy exceeds two classes.
      The whole ErrorOutput can be found attached.
