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.
