The exception clearly states the problem: "This server does not appear to be compiled for production mode". You are attempting to run in production mode with a server compiled in dev mode. You either need to start this webapp in dev mode (-Ddevmode=true) or compile a production build. See the Creating Production Builds page.

Also, I strongly suggest following all the recommendations on the Supported Technologies page. This shows the versions of all dependencies that we have tested thoroughly for compatibility. In particular, recently released Tomcat 8.0.37 introduced a change that causes our build to fail. At this point, we have addressed the problem only on the release16.2 branch.
