FULL PRODUCT VERSION :
java version "1.4.0_01"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0_01-b03)
Java HotSpot(TM) Client VM (build 1.4.0_01-b03, mixed mode)

FULL OPERATING SYSTEM VERSION :
Microsoft Windows 2000 [Version 5.00.2195]

A DESCRIPTION OF THE PROBLEM :
I would like to delegate all of my interface
implementations to another class or adapter, ideally
through a new keyword. Example below:

public interface intefaceA {
  void methodA();
  void methodB();
}
public class InterfaceAAdapter
  implements InterfaceA
{
   public void methodA(){}
   public void methodB(){}
}

class ClassA implements InterfaceA
{
// new keyword here
  delegate InterfaceA myInterfaceA;
  InterfaceAAdapter myInterfaceA;
}

This would basically add the following methods to ClassA at
compiletime

  methodA(){ myInterface.methodA();}
  methodB(){ myInterface.methodB();}

It would be very simple to implement in the compiler
(similar to Innerclasses) and would drastically clean up
code all over the world. Take for instance java beans
which continually use utility class for property
management, only to expose the function via wrapper.

I use this model of support pops-up as useful all over the
place. This would probably solve most areas where a static
method in an interface would be used.

Don't force developers to rely on a tool kit for this
support. Inner classes could also be done via raw coding.



REPRODUCIBILITY :
This bug can be reproduced occasionally.

CUSTOMER WORKAROUND :
Currently I can manually code all of the methods to
interface.
