        Description

        Server-class machine ergonomics was introduced in jdk5. If the machine upon which
        the jvm is running is powerful enough (currently, at least 2 physical cores plus
        at least 2gb of memory), the server jvm is invoked using the parallel scavenger
        rather than the serial scavenger. Currently the old gen collector used is
        serial mark-sweep-compact. Now that the parallel old gen collector is mature,
        we should change to using it instead.
