In Eclipse Jetty 9.4.32 to 9.4.38, 10.0.0.beta2 to 10.0.1, and 11.0.0.beta2
to 11.0.1, if a user uses a webapps directory that is a symlink, the
contents of the webapps directory is deployed as a static webapp,
inadvertently serving the webapps themselves and anything else that might
be in that directory.
