the problem is when invoking  instance.getClass() the object instance is null

[diegocoronel]

i saw that it return null because this condition:

   /**
    * Gets the receiver of the product
    * 
    * @return The receiver
    */
   protected Object getReceiver(CreationalContext<?> creationalContext)
   {
      // This is a bit dangerous, as it means that producer methods can end of
      // executing on partially constructed instances. Also, it's not required
      // by the spec...
      if (getAnnotatedItem().isStatic())
      {
         return null;
      }

Please file an issue with a test case, and we'll fix that...
