[7.0.0-M3] Error message

When catching a FileUploadException in the 
AbstractMultiPartRequest.parse() method, if the final "else" is reached, 
the default message 
"struts.messages.upload.error.FileUploadException=Error uploading: {0}!" 
(struts-messages.properties) always displays the "{0}" instead of 
replacing it with the actual filename.  In looking at the code, it might 
be difficult to bubble up the filename from the source of the exception, 
but that would be the preferred solution.  Otherwise, it might make 
sense to change the default upload error message without the {0} 
parameters (e.g. "Error uploading the file", or "Error parsing the 
request."). Thoughts?
