> Project: Calcite

>
> Http Sessions created by the Avatica server are never expired.
> This eventually causes the Avatica server to OOM.
> Well designed clients using long-lived sessions may never generate enough
> sessions between server restarts for this to become apparent, but ill-behaved
> clients creating a lot of sessions can fill the heap in a short time.
> As the Jetty default (when not using the web.xml descriptor) is infinite
> lifetime, we need to set a reasonable default idle timeout when setting up
> Jetty Session handling.
