This should go to the logger category for the Context, logged as ERROR
level, as it will be logged through the servlet context. Maybe there's
a problem somewhere, but I find it hard to believe. You can look at
the code in StandardContext.listenerStart, ApplicationContext.log and
in ContainerBase.getLogger: this looks very straightforward.
You can send me a test war if you think it doesn't work.
