Ahm - this is more like a general problem of Java ... Java takes a lot of memory and ... well I'm not sure there's something you can do about it.
I just tried writing a micro java program which sleeps five seconds and exits ... on my machine to run it takes 8 threads recorded using 140 Mb of virtual memory each, though in reality each of them takes `only' 5.8 Mb of resident memory size. This is pretty consistent with running java/Testing/ObjC/obj/JavaTest, which - after starting the JVM - takes 5 threads recorded at 73 Mb each ... though each takes only 6.2 Mb of resident memory size. So I'm not surprised you get a footprint of 57Mb. It is important to determine which is the RSS though - it's probably around 5 Mb. About your questino - yes, you can pass options to the JVM when you start it (see the documentation for JNI_CreateJavaVM) - you can probably put them in by modifying java/Source/NSJavaVirtualMachine.m - and your JVM might have options to determine memory constraints, but I suspect it's not going to help at all ... and even if you are able to run it in less memory, that might well make it hugely slower. > How to reduce the initial foot print( memory) of JVM embedded in a > ObjectiveC component(AlarmServer) through JNI.The objectiveC component is > showing around 36Mb with 1.1.8 JRE and 57Mb with 1.3 JRE.
