The CVS version works for the original Bug.java, but still
causes NoSuchMethodError for the following code compiled
with Sun's javac.

public class Bug {
     interface SupInterface {
        void foo();

     interface Interface extends SupInterface {

     static abstract class Abstract implements Interface {
        public void bug() { foo(); }

     static abstract class Abstract2 extends Abstract {

     static class Impl extends Abstract2 {
        public void foo() {}

     public static void main(String[] args) {
          (new Impl()).bug();

java.lang.NoSuchMethodError: Bug$Abstract.foo()V
        at Bug$Abstract.bug(Bug.java:10)
        at Bug.main(Bug.java:21)
