Coping methods

Hi

I noticed that when a MethodGen is copied from one class (One) to 
another (Another), all references to this are left unchanged:

class One {
   int field;
   void putfield() {
     field = 10
   }
}

after copy of the putfield() method to Another I get smth like (I am 
decompiling by hand):
class Another {
   //....
   void putfield() {
   One one;
   one = this;
   one.field = 10;
   }
}

which makes the JVM verifier nervous.

Is that way of copy feature or a bug. If a bug, will it be fixed soon/ 
would you receive patch.
