Description

According to jetty sources:

public Server(@Name("threadpool") ThreadPool pool)
{
    _threadPool = pool != null ? pool : new QueuedThreadPool();
    addBean(_threadPool);
    setServer(this);
}

When we instantiate Server class via xml we need to use threadpool (all lowercase) instead of threadPool

<Configure id="Server" class="org.eclipse.jetty.server.Server">
    --- <Arg name="threadPool">
    +++ <Arg name="threadpool">
    ...

otherwise we would get an error:

Caused by: java.lang.IllegalStateException: No matching constructor class org.eclipse.jetty.server.Server in file:///...config/jetty.xml
