<p class=MsoNormal>The problem seams to happen because the kagent can't access
the url. <o:p></o:p></p>
<div>
<p class=MsoNormal>If you try to access the change set xml using a browser,
does the browser ask you for authentication? I don't know why, but guvnor
protect its urls since 5.1 I think. <o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>So, basically, the error is that guvnor can't read from the
url. The same error happens if you provide a non existent url. I need to open a
jira for this.<o:p></o:p></p>
