java.lang.ClassNotFoundException: org.apache.coyote.http11.Http11Protocol

Question

After upgrading Apache tomcat from 9.0.48 to 9.0.62 version My application started throwing following error :-

org.apache.catalina.startup.Catalina.stopServer Error stopping Catalina
    org.apache.catalina.LifecycleException: Failed to stop component [StandardService[Catalina]]

[main] org.apache.catalina.connector.Connector.<init> Protocol handler instantiation failed
    java.lang.ClassNotFoundException: org.apache.coyote.http11.Http11Protocol

I've checked the /conf/server.xml file also , it correctly uses the connector protocol

<Connector port="8443" protocol="org.apache.coyote.http11.Http11Protocol"
               maxThreads="150" SSLEnabled="true" scheme="https" secure="true"
               clientAuth="false" sslProtocol="TLSv1.2" />

Not sure what is causing this error.
