---- ACTION DETAILS ----

Action Performed:
1. Install Tomcat 8.5.28 as per directions in Alfresco Docs ( https://docs.alfresco.com/5.2/tasks/configfiles-change-path.html )
2. Deploy ACS 6.0 as per directions in https://docs.alfresco.com/5.2/tasks/alf-war-install.html
3. Start Alfresco Server

Expected Result:
The server should start with no errors

Actual Result:
Alfresco fails to start due to an compatibility between the config files supplied in the ACS 6.0 Distribution zip and Tomcat 8

The issue appears to be with the following files in the distribution zip
web-server/conf/Catalina/localhost/alfresco.xml
web-server/conf/Catalina/localhost/share.xml

Additional Info:
Distribution Zip used: alfresco-content-services-distribution-6.0.0-RC3.zip

According to Tomcat 8 Migration guide ( https://tomcat.apache.org/migration-8.html#Web_application_resources ) The VirtualLoader has been replaced in Tomcat 8
" The Aliases, VirtualLoader, VirtualDirContext, JAR resources and external repositories features that all provided a way to add resources to a web application have been replaced with a single framework rather than each being implemented separately (this was becoming increasingly difficult to maintain). The resources documentation provides details on how the new implementation may be used."
