I am moving an app from tomcat 9.0.100+ to 11.0.5. The conversion tool
worked well and quickly got to a clean compile. At Tomcat.start() I get
a stacktrace mentioning jasper. There are no JSPs in my system:
SEVERE: Servlet [jsp] in web application [/sgs] threw load() exception
java.lang.ClassNotFoundException: org.apache.jasper.servlet.JspServlet
