            Ideally this dependency should have been added with 'compile' scope here. But that is causing 'java.lang
            .NoClassDefFoundError'. After trying to fix it right way many times, I decided to move the dependency to
            the main server module's pom.xml file and keep the dependency here with 'provided' scope. This seems to
            fix the problem for now.
