i have a dillema where my jetty configs led me to a certain configuration
but the PushCacheFilter does not work on launch, it throws an NPE.
i use a restapi that previously inheritted defaultservlet and served the
static content itself, and this worked well for PushCacheFilter though i
did not want to duplicate the welcomefiles functionality and so refactored
to this now.
TIA
