Precompiling JSPs for Tomcat

It often happens that JSP page doesn't compile and we don't know about that until we open it. This delays the feedback. What we want is to include a pre-compilation of JSP pages to the CI Build to check whether they compile right away. If they don't, the build will fail.
Another bonus will be detecting of stale JSP pages that are not used. At some point those won't be compiled because the classes they are using are not there anymore and we'll detect whether such an old page is present.

Note, that we're not going to actually put pre-compiled pages into WAR file since they won't going to work on other app servers.

This task is to find a means to do precompilation with Maven + Tomcat.
