The problem is that a subclass can't see the superclass's protected inner 
class. In summary, here's the problem:

public class A {
    public class Inner {
        protected class NestedException {}
    }
}

public class B {
    public class Inner extends A.Inner {
        --- in here, can't see the A.Inner.NestedException type,
            even though we're a subclass of A.Inner ---
    }
}

---

Java files exhibiting the problem follow. They are:
    util/A.java
    client/B.java
Both compile fine with JDK 1.3.1_01, won't compile with Eclipse 2.0 build 
20011206.

--- util/A.java ---
package util;

public class A {
	public abstract static class Inner {
		protected final static class NestedException extends Exception {
            public static void rethrow(final Throwable throwable)
                throws NestedException
            {
              throw (NestedException) throwable;
            }   
		}
	}
}


--- client/B.java ---
package client;

import java.io.Serializable;

import util.A;

public class B
{
    private final static class Inner extends A.Inner
    {
        protected final void construct()
            throws A.Inner.NestedException
        {
			A.Inner.NestedException.rethrow(new Exception());
        }
    }
}
