import org.apache.catalina.connector.Request;

This causes java doc plugin to fail when the transitive tomcat jars are missing. As a temporary fix, we have added the below transitive dependency,

<dependency>
            <groupId>org.apache.tomcat</groupId>
            <artifactId>tomcat-coyote</artifactId>
            <version>7.0.69</version>
</dependency>

Ideally, we should refactor this class and get rid of this dependency.
