The following test case fails to compile in AspectJ 1.1 beta 4, and works 
correctly in AspectJ 1.0. The only work around is to make interfaces public, 
which is a serious problem.

file TransactionControl.aj (default package):
import sub.ObserverProtocol;

aspect TransactionControl {
    void begin() {
        CommitObserver.aspectOf().add(this);
    }
    static aspect CommitObserver extends ObserverProtocol {
        declare parents: TransactionControl implements Observer;
    }
}

file sub/ObserverProtocol.aj
package sub;

public abstract aspect ObserverProtocol {  
    protected interface Observer { }
    public void add(Observer o) {}
}

Sample compilation:
C:\devel>ajc sub\ObserverProtocol.aj TransactionControl.aj
can't bind type name 'Observer'
C:/devel/TransactionControl.aj:5: The method add(sub.ObserverProtocol.Observer)
in the type sub.ObserverProtocol is not applicable for the arguments (Transactio
nControl)
CommitObserver.aspectOf().add(this);
                          ^^^
