Why is Commons Logging included in the webapp class loading filter?

Issue

On Jboss, any messages logged via the commons-logging API are swallowed up and not logged out using my own logging configuration.
The reason is that the ./deployers/jbossweb.deployer/META-INF/war-deployers-jboss-beans.xml defines two packages that should never be loaded by the webapp class loader - javax.servlet (no surprises there) and org.apache.commons.logging. Can you provide the reason for JBoss does not load commons.logging? I have found my application, and it's logging works OK by removing commons.logging from the filteredPackages list in this file.
