BTW I have read recently that on Windows you can't get more than approximatly 1.5GB of Heap See here for instance : http://www.velocityreviews.com/forums/t144234-help-ltgc-reduced-max-java-heap-size-to-bytes-due-to-memory-contraintsgt-.html The explanation come from the implementation of the garbage collector : it needs an continuous segment of memory.
