* if servletContext.getRealPath() returns null you are using an unexpanded
war in a container where magnolia will not run unexpanded.
* If you are using a expanded war or a unexpanded war in a server where
magnolia can run you will never see this message. If
servletContext.getRealPath() returns null it means that you are running a
unexpanded war in a server where this is not supported and the log clearly
helps you in fixing your configuration.

My take on this is as follows:
* if {{servletContext.getRealPath()}} returns null, either server is not
configured properly or magnolia is not configured properly (if it still relies
on the value). And configuration change doesn't necessarily mean that you have
to expand the war file. It can be many different things, for example Weblogic
10 has a flag that can be put in deployment descriptors specifying if you want
to get real value or not.
So the statement in the error message ??Magnolia needs to be run from an
expanded webapp?? is not correct. The correct message in this case would be
"_Real path can't be obtained. Magnolia is not configured properly and
therefore unable to start. Please refer to Magnolia documentation for
installation instructions specific for your environment (OS, app server)._"
