[exitNA]

after link war file to tomcat webapps dir, I open the page from http://localhost:8080/Larex/, got those java exceptions:

This seems to be related to #239

Building LAREX for Java 8 should resolve this (I just saw that we don't explicitly state this in our README, I'll change this).

In case building for Java 8 didn't fix the problem, feel free to reopen the issue.
