How to enable CachingWebAppClassLoader in Jetty Maven plugin?

Question

I am trying to improve the performance of running a Java web application in a development environment. It uses plugty-maven-plugin and is mvn jetty:runused to run the application.

I followed the instructions http://www.eclipse.org/jetty/documentation/9.3.x/jetty-classloading.html to register this new one CachingWebAppClassLoader.

<Configure id="mywebapp" class="org.eclipse.jetty.webapp.WebAppContext">

...

  <Set name="classLoader">
    <New class="org.eclipse.jetty.webapp.CachingWebAppClassLoader">
      <Arg><Ref refid="mywebapp"/></Arg>
    </New>
  </Set>

...
</Configure>

However, org.eclipse.jetty.webapp.WebAppClassLoader.*continued to appear in jplvvvmv but notCachingWebAppClassLoader

I confirmed that my registration of the class loader was at least detected by providing an invalid class name, in which case it ClassNotFoundExceptionwas selected. I assume that my classloader configuration is being consumed, but not used or something like that. Any ideas?
