Trailing slash issue

When accessing the webapp without the trailing slash after the context http://localhost:8080/magnoliaAuthor after login the user is presented with a 404 page rather than admincentral.  This behavior is configurable via the mapperContextRootRedirectEnabled and mapperDirectoryRedirectEnabled attributes of the Context which may be used to restore the previous behavior. See Apache Tomcat 7 ChangelogSee Tomcat 9.0.0.M2 in https://tomcat.apache.org/tomcat-9.0-doc/changelog.html.
