20-Dec-2017 14:58:59.135 WARNING [main] org.apache.catalina.startup.Catalina.load Catalina.start using conf/server.xml: Error at (30, 67) : org.apache.catalina.core.JasperListener

How to fix #1

• simply REMOVE obsolete setting from server.xml

conf/server.xml

<Listener className="org.apache.catalina.core.JasperListener" />

cf
https://tomcat.apache.org/tomcat-8.0-doc/changelog.html
Initialize the JSP runtime in Jasper's initializer to avoid need for a Jasper-specific lifecycle listener. JasperListener has been removed. (jboynes)
