My humble guess is that both Jsr168Dispatcher and Dispatcher are cleaning the context; so the last one being called gets a null reference because the previous dispatcher already performed the clean.

As a side note, if you are not able to depoy on jboss, please remove the commons-logging jar from the sample portlet war file.
