Using Unity 2.0 handle exception

When I use Unity 2.0 to handle exception, I got some problem, like below:

public class TraceBehavior : IInterceptionBehavior
{
    public IEnumerable<Type> GetRequiredInterfaces()
    {
        return Type.EmptyTypes;
    }

    public IMethodReturn Invoke(IMethodInvocation input, GetNextInterceptionBehaviorDelegate getNext)
    {
        Console.WriteLine(string.Format("Invoke method:{0}",input.MethodBase.ToString()));
        IMethodReturn result = getNext()(input, getNext);
        if (result.Exception == null)
        {
            Console.WriteLine("Invoke successful!");
        }
        else 
        {
            Console.WriteLine(string.Format("Invoke faild, error: {0}", result.Exception.Message));
            result.Exception = null;
        }
        return result;
    }

    public bool WillExecute { get { return true; } }
}

I have set result.Exception=null (it's meaning that I have resolved the exception and need not throw again.)
However,it throw a exception to me.

That's not how it works. Don't set result.Exception, instead return input.CreateMethodReturn(newReturnValues).
