The number of concurrent connections to Jetty is 1 in this particular case :)
The error message below is being thrown out after Jetty goes into some kind of infinite loop, apparently opening lots of file descriptors...

Alexander,
What's the number of open file descriptors that you have configured
for your operating system? Perhaps the number is set too low for the number of concurrent connections?

Is that a bug ?
My code
Server server = new Server(8080);
ServletContextHandler context = new ServletContextHandler(ServletContextHandler.SESSIONS);
context.setContextPath("/");
server.setHandler(context);
context.addServlet(new ServletHolder(new JettyScreenshotProxyServlet()), "/");
server.start();
server.join();
