Precise explanation by Saif asif.

I was using gradle as the build tool. It worked for me to exclude the tomcat-servlet-api.jar which is by default provided by tomcat.

You need to know which of your dependency is transitively adding tomcat-servlet-api.jar to the war and then exclude it using following

 compile ('your dependency goes here') {
        exclude module:'tomcat-servlet-api'
    }
