As noted, and corrected in the Java code example above, the threadpool is now provided as a constructor argument in Jetty 9 (and later).

The corrected XML example:

<Configure id="Server" class="org.eclipse.jetty.server.Server">

    <!-- =========================================================== -->
    <!-- Configure the Server Thread Pool.                           -->
    <!--                                                             -->
    <!-- Consult the javadoc of o.e.j.util.thread.QueuedThreadPool   -->
    <!-- for all configuration that may be set here.                 -->
    <!-- =========================================================== -->
    <Get name="ThreadPool">
        <Set name="minThreads" type="int">10</Set>
        <Set name="maxThreads" type="int">200</Set>
        <Set name="idleTimeout" type="int">60000</Set>
        <Set name="detailedDump">false</Set>
    </Get>
    ...

From docs:

The Server instance provides a ThreadPool instance that is the default Executor service other Jetty server components use. The prime configuration of the thread pool is the maximum and minimum size and is set in etc/jetty.xml.

<Configure id="server" class="org.eclipse.jetty.server.Server">   
<Set name="threadPool">
    <New class="org.eclipse.jetty.util.thread.QueuedThreadPool">
      <Set name="minThreads">10</Set>
      <Set name="maxThreads">1000</Set>
    </New>
</Set> 
</Configure>

Or

QueuedThreadPool threadPool = new QueuedThreadPool(100, 10);
Server server = new Server(threadPool);
