[jetty-users] New HttpClient holds resources

[ccleve <ccleve.tech@xxxxxxxxx>]

I'm writing code that uses the new Jetty 9 HttpClient. Unfortunately, 
you have to start() it and later stop() it, else it holds resources and 
doesn't let the JVM stop. (I assume it's got some threads still running 
internally.)

Is this really necessary? Or is it an essential element in an Async NIO 
implementation?

I'm concerned about resource leaks.
