Why do these methods in Component return Object, not a type?

   public static Object getInstance(Class<?> clazz)
   {
      return getInstance(clazz, true);
   }

   public static Object getInstance(Class<?> clazz, boolean create)
   {
      return getInstance( getComponentName(clazz), create );
   }

   public static Object getInstance(Class<?> clazz, ScopeType scope)
   {
      return getInstance(clazz, scope, true);
   }

   public static Object getInstance(Class<?> clazz, ScopeType scope, boolean create)
   {
      return getInstance( getComponentName(clazz), scope, create );
   }

Ordinarily, you would do:

   public static <T> T getInstance(Class<T> clazz)
   {
      return (T)getInstance(clazz, true);
   }

Would help catch bugs I think.
