I like this little gem:

$ for jar in $CATALINA_HOME/lib/*.jar ;
  do echo "$jar" ;
  unzip -v "$jar" | grep RemoteAddrFilter" ;
  done

This will print a list of all the JARs (I'm sure there is a way to
suppress the ones that don't match) and then, underneath the one that
matches, you'll see the file:

/apache-tomcat-8.0.46/lib/annotations-api.jar
/apache-tomcat-8.0.46/lib/catalina-ant.jar
/apache-tomcat-8.0.46/lib/catalina-ha.jar
/apache-tomcat-8.0.46/lib/catalina-storeconfig.jar
/apache-tomcat-8.0.46/lib/catalina-tribes.jar
/apache-tomcat-8.0.46/lib/catalina.jar
    1935  Defl:N      740  62% 08-10-2017 13:11 cf250a0f
org/apache/catalina/filters/RemoteAddrFilter.class
/apache-tomcat-8.0.46/lib/ecj-4.6.3.jar
/apache-tomcat-8.0.46/lib/el-api.jar
...

So you can see that catalina.jar contains the file.

I like this better just in case the filename has been mangled in some
way inside of the JAR file (even though it shouldn't be).
