Struts Menu 2.4.2   error in   Struts 2

I am using  Struts Menu 2.4.2  with Struts 2.
I am configuring it as deploying the menu framework outside of Struts (1.x that is.)

I have everything working like a champ, except every screen call/refresh produces the following error:

{
ERROR [UseMenuDisplayerTag] Can't find bundle for base name org.apache.struts.action.MESSAGE, locale en_US
}

- -  This is a Struts class producing the message.


This does not stop the application, but I want to eliminate this message / exception written to the Log.
How do I do that?
