This is to strict, it should be INFO or even less.
What we're trying to do here is get a real (non-temp) URL, for that we use original handler.
And then try to get a child off this old handler, where since removed, is null.
So we try our best to re-ceate the original url - hence warning.
This can occur in normal operations such as when using a jboss-structure.xml:
<structure>
<context modification="temp">
<path name=""/>
<metaDataPath>
<path name="WEB-INF"/>
</metaDataPath>
<classpath>
<path name="WEB-INF/classes"/>
<path name="WEB-INF/lib" suffixes=".jar"/>
</classpath>
</context>
</structure>
And if you deploy an exploded deployment and then remove it from the deploy directory triggering a undeploy will cause the warning.
