//MethodDeclaration
[
MethodDeclarator/@Image = 'clone'
and count(MethodDeclarator/FormalParameters/*) = 0
and count(NameList/Name[contains
(@Image,'CloneNotSupportedException')]) = 0
]
[

 public class MyClass implements Cloneable{
     public Object clone() { // will cause an error
          MyClass clone = (MyClass)super.clone();
          return clone;
     }
