Local fix

Problem summary

• the code generated for inheritance in rule task  does not work
  properly and can have a class and its parent declare the same
  final method which creates the verifyError when loading the
  code.
  

Problem conclusion

• the generation of inheritance is fixed
  

Temporary fix
