Java HotSpot Virtual Machine

Hi,

Have a problem getting the JAVA_OPTS env-parameter to work.

I am on a Windows XP system with JRE 1.6.0_12, and have written a test-class:

package info;

import java.lang.management.ManagementFactory;
import java.lang.management.MemoryUsage;

public class MemInfo {

	public static void main(String[] args) {
		MemoryUsage mu = ManagementFactory.getMemoryMXBean()
				.getHeapMemoryUsage();

		Long mIni = mu.getInit();
		Long mMax = mu.getMax();
		Long mUse = mu.getUsed();

		System.err.println("ini=" + mIni);
		System.err.println("max=" + mMax);
		System.err.println("use=" + mUse);
		System.err.println(mu.toString());
	}
}

When I run it with:

  java -Xms1g -Xmx1g info.MemInfo

I get the expected output (max heap size=1GB):

ini=1073741824
max=1065484288
use=1321224
init = 1073741824(1048576K) used = 1321224(1290K) committed = 1065484288(1040512K) max = 1065484288(1040512K)

But when I try to do the same, using JAVA_OPTS:

set JAVA_OPTS=-Xms1g -Xmx1g
java info.MemInfo

I get the default values output (max heap size=1GB) :

ini=0
max=66650112
use=206032
init = 0(0K) used = 206032(201K) committed = 5177344(5056K) max = 66650112(65088K)

Isnt JAVA_OPTS supposed to work like this?
Or what am I missing?
