Here is a piece of code that works with javac but throw an error in eclipse 
(3.1M6) 
 
public class Test { 
    public abstract class Context <N extends Number> { 
        private Strategy < N , ? super Context<N> > strategy; 
        public void setStrategy(Strategy < N , ? super Context<N> > strategy) 
{ 
            this.strategy = strategy; 
        } 
        // méthode qui utilise la stratégie 
        public N call() throws Exception { 
            return this.strategy.call(this); 
        } 
    } 
    public interface Strategy < N extends Number , C extends Context<N> > { 
        public abstract N call(C context); 
    } 
 
} 
 
The error is thrown at each line (two in fact) with the super keyword : 
Bound mismatch: The type ? super Test.Context<N> is not a valid  
 substitute for the bounded parameter <C extends Test.Context<N>> of  
 the type Test.Strategy<N,C>
