[S2] Possible Bug in FileUploadInterceptor

["Hoying, Ken" <Ke...@PremierInc.com>]

There appears to me to be an annoying bug or what I believe to be a bug
in the FileUploadInterceptor.  On line 311, if the file does not pass
the file validation the error message is retrieved as such:

	String errMsg =
getTextMessage("struts.messages.error.file.too.large", new
Object[]{inputName, file.getName(), "" + file.length()}, locale);

The issue that I have with this is that file.length has been converted
to a String.  This now makes it impossible to format it as a number in
your message.  

	struts.messages.error.file.too.large=You attempted to upload a
{2,number} byte file.

A rather insignificant issue, but one that would be nice to see fixed in
the future.

Thanks!
