Hi, does anyone know where I can find a good description of the "non-standard" options -X ????? I am especially interested in further information concerning: -Xrunhprof[:help]|[:<option>=<value>, ...] perform heap, cpu, or monitor profiling -Xdebug enable remote debugging -Xfuture What happens by enabling remote debugging or -Xfuture??? Is there a disadvantage by disabling class garbage collection?? In which cases should I do this??
