I confess that I don't understand the portal environment very well, but if I'm following this correctly then PLUTO-553 is a symptom of a more fundamental issue: objects in a Pluto portlet cannot rely on the context classloader to be the correct one from which to obtain resources. This arises because -- as I understand it -- Pluto provides portlet isolation analogous to the isolation of distinct webapps in a servlet container, but unlike a servlet container, it allows one portlet to invoke methods on the live objects of another, not changing the context classloader when such cross-context method invocations occur.
If I have analyzed that correctly then I would account it a Pluto bug, not a JCL bug.

It is documented at http://issues.apache.org/jira/browse/PLUTO-553. In a nutshell though, the Portal is a War. Individual portlets are packaged as separate war files and are run under the direction of the main portal war. They seem to want all the portlets to use the logging configuration of the portal. Personally, I'm not sure what they are saying they want makes sense, but I guess the point is that even if it doesn't they should still be able to do it.
