Javadoc
This method will create a path relative to the '/WEB-INF/classes/' folder
for the given path. It will first try to find the '/WEB-INF/classes/'
suffix in the path to do so. If this suffix cannot be found (can happen
when using the jetty-maven-plugin with 'jetty:run' goal), the method will
try to build the relative name by stripping the path of the
'/WEB-INF/classes/' folder which must be supplied to the method. The
method will throw an
IllegalArgumentException if the relative path
could not be build.
