Hello!
Under load testing of our application I'm seeing that Jetty spawned exactly 800 threads instead of only 200 as per my configuration. How can this happen? What am I missing?
We use 9.0.4 in Equinox with a jetty.xml taken from Jetty's git:
<Configure id="Server" class="org.eclipse.jetty.server.Server">
<!-- =========================================================== -->

</Configure>
p.s. I just noticed that idleTimeout is not set for thread pool - can this cause issues like this? I will set it to 60000 but versions of jetty.xml in git should probably be corrected too. And maybe a sane default should be placed in source code?
