I believe this to be the same issue as I am having with sshexec putting a
linefeed, cr, or both.  If this antuser would have put an echo on his
property like so:

<echo message="XXX${return_code}XXX"/>

He would have seen that there's a cr stuck in there.  It does the same with
output when you put it in a text file.  I had it do that, then opened the
text file in notepad and saw the funky character on the end of the output. 
The resulting property ends up being "uncomparable" because of the special
character on the end.
