  • How would I check if the environment I inherited is using a GC
    algorithm in Jetty?
    I searched for 'parallel', and also for 'garbage' in Jetty's etc
    directory and did not come up with anything.
    I am assuming if it was specified it would be in Jetty.XML or perhaps start.ini?
    Thanks
