Similar to bug #4100959, but stack trace is different after 3rd line or so. So I'm treating it as different.

My code is probably unusual.. I am defining a set of interfaces for general data transfer.
They use nested interfaces that inherit other interfaces with nested interfaces. These interfaces also extend their contained interfaces
For example:

public interface Base extends Base.Foo, Base.Bar{
   public interface Foo{
      ...
   }
   public interface Bar{
      ...
   }
}

public interface Child extends Base, Child.Foo, Child.Bar{
   public interface Foo extends Base.Foo{
      ...
   }
   public interface Bar extends Base.Bar{
      ...
   }
}

The idea is so that one could extend the entire Child interface by implementing Child, or just a subset by implementing Child.Foo.

I did a simple test program to see if the above was possible. The simple test program compiled ok.
Only when I had an inheritance of about 3 deep did problems occur. If you read this and you want me to email you my
code, then contact me. I dont think it wise for me to publish the code for the world to see.


Here's the stack trace:
