If loading showcase in any browser using SSL (https://localhost:8443/showcase), there is a server-side error each time the user clicks on any link to access ACE components; however the pages are loaded and no functional issues could be found so far.

This error is not thrown if after starting tomcat and showcase deployment, the non-SSL showcase URL is loaded first (http://localhost:8080/showcase), and then the SSL showcase is accessed (https://localhost:8443/showcase).
