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)
