is ajp12 connection handler required to shutdown?

[Morianos]

I don’t want to use the ajp12 protocol but if I leave it out of the server.xml file(s) I can’t shut tomcat down cleanly.  The docs state that this is needed to shut down tomcat properly but if I am running multiple JVMs with multiple server.xml files, that means I need multiple ajp12 connectors.  One for each JVM.  Am I understanding this correctly?
