If you are interested in how this can be achieved, have a look at http://www.aicas.com/ They sell a real-time capable VM. Of course you cannot expect real-time behaviour from a standard VM from Sun on a non-real-time OS like Windows. Nevertheless the statement that Java stops for minutes to do some garbage collection is simply wrong for modern VMs. Michael
