move to tomcat 11, now see a jasper dependency

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
