Jetty priority treatment of health checks? - jetty

Question

My Jetty is servicing requests on /myservice/*
My problem is that when the server's queue gets full, the health check requests on /healthcheck start failing.
Is it possible to have a separate queue for my health checks, or is there another way to do this?import java.io.IOException;
Here is an example server:
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.eclipse.jetty.server.Server;
import org.eclipse.jetty.servlet.ServletHandler;
import org.eclipse.jetty.util.thread.QueuedThreadPool;
/**
* Based on:
* https://www.eclipse.org/jetty/documentation/9.4.x/embedded-examples.html
*/
public class HealthCheckServer
{
public static void main( String[] args ) throws Exception
{
Server server = new Server(8086);
QueuedThreadPool qtp = (QueuedThreadPool) server.getThreadPool();
qtp.setMaxThreads(6);
ServletHandler handler = new ServletHandler();
server.setHandler(handler);
handler.addServletWithMapping(HelloServlet.class, "/hello");
handler.addServletWithMapping(HealthServlet.class, "/health");
server.start();
server.join();
}
#SuppressWarnings("serial")
public static class HelloServlet extends HttpServlet
{
#Override
protected void doGet( HttpServletRequest request,
HttpServletResponse response ) throws ServletException,
IOException
{
try {
Thread.sleep(10*1000); // 10 sec
} catch (InterruptedException e) {
e.printStackTrace();
}
response.setContentType("text/html");
response.setStatus(HttpServletResponse.SC_OK);
response.getWriter().println("<h1>Hello from HelloServlet</h1>");
}
}
#SuppressWarnings("serial")
public static class HealthServlet extends HttpServlet
{
#Override
protected void doGet( HttpServletRequest request,
HttpServletResponse response ) throws ServletException,
IOException
{
response.setContentType("text/html");
response.setStatus(HttpServletResponse.SC_OK);
response.getWriter().println("all good captain");
}
}
}
If you hit http://localhost:8086/hello 4 times, then http://localhost:8086/health won't be responsive.
