java.lang.NoClassDefFoundError is thrown in case of having a tomcat cluster with session replication with session replication activated:

Steps to reproduce - environment setup

1. Configure Liferay cluster with two tomcat nodes.
2. Edit $TOMCAT_HOME/conf/server.xml of each node and configure the tcp ports to "8080" and "8180"
3. Activate session replication at tomcat level:
   1. Edit $TOMCAT_HOME/conf/server.xml of each node and inside Engine tag, add following text:

      <Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster"/>
      

   2. Edit $TOMCAT_HOME/conf/context.xml of each node and inside Context tag, add following text:

          <Manager className="org.apache.catalina.ha.session.DeltaManager"
                   expireSessionsOnShutdown="false"
                   notifyListenersOnReplication="true"/>
      

   3. Edit $TOMCAT_HOME/webapps/ROOT/WEB-INF/web.xml and immediately following the <web-app> tag (inside the tag), add the tag <distributable />
   4. Edit $TOMCAT_HOME/conf/logging.properties and add the following lines.

      ##CLUSTER LOG
      5cluster.org.apache.juli.AsyncFileHandler.level = FINER
      5cluster.org.apache.juli.AsyncFileHandler.directory = ${catalina.base}/logs
      5cluster.org.apache.juli.AsyncFileHandler.prefix = cluster.
      
      # just the clustering logs - all others are stock logging.properties
      org.apache.catalina.tribes.MESSAGES.level = FINE
      org.apache.catalina.tribes.MESSAGES.handlers = 5cluster.org.apache.juli.AsyncFileHandler
      
      org.apache.catalina.tribes.level = FINE
      org.apache.catalina.tribes.handlers = 5cluster.org.apache.juli.AsyncFileHandler
      
      org.apache.catalina.ha.level = FINE
      org.apache.catalina.ha.handlers = 5cluster.org.apache.juli.AsyncFileHandler
      
      org.apache.catalina.ha.deploy.level = INFO
      org.apache.catalina.ha.deploy.handlers = 5cluster.org.apache.juli.AsyncFileHandler
      

   5. Also add 5cluster.org.apache.juli.AsyncFileHandler to handlers line at the beggining of the file.

Steps to reproduce

1. Start first tomcat node and wait until startup finish
2. Verify you can login from browser using URL: http://localhost:8080/web/guest
3. Start second tomcat node and wait until startup finish
4. Review LIFERAY_HOME/tomcat-8.0.32/logs/cluster.2017-xx-xx.log files of both nodes (configured in previous steps) and verify that tomcat cluster is working.
5. Login and logout in both tomcat cluster nodes using following URLs: http://localhost:8080/web/guest and http://localhost:8180/web/guest
6. Check again cluster log files of both:
   • Correct behavior: No error is displayed
   • Wrong behavior: Following error is displayed in some session event replication, in the opposite node
     (if you login in first node, error is displayed in second one and vice-versa)
