Resolution

000100929 - Any issue with CA-Web Viewer and JDK 1.8? - Tech Doc helped resolve issue. Customer opened a case with IBM, and IBM found user.dir has no value in the logs: user.dir = . The explanation was: JAVA8 enforces a valid user.dir while JAVA6 not. Correcting this was the ultimate resolution.

Additional Information

This was not a Web Viewer problem. It turned out to be a USS, Java 8, WebSphere environment configuration issue, meaning it would affect any web application trying to run in that environment.
