JVM cant allocate enough memory .

Case Code as below:
_____________________________________________________________

public boolean chekForHeapSize(int ms, int mx) {

        System.out.println("Inside mode "+mx + " " + ms);

        Runtime rt = Runtime.getRuntime();

        if( rt.maxMemory() > (mx * 1024 * 1000) &&

            rt.totalMemory() > (ms * 1024 * 1000) ) {

            System.out.println("STATUS: "+ testName + " PASSED");

            return true;

        } else {

            System.out.println("STATUS: "+ testName + " FAILED");

            return false;

        }

__________________________________________________________________

 

I ran this command

 

java client Xms60m Xmx70m memory.java

 

_________________________________________________________________

(memory.java:code)

public class a {

   public static void main(String[] args) {

             String vmname = System.getProperty("java.vm.name");

             long totalM = Runtime.getRuntime().totalMemory();

             long maxM = Runtime.getRuntime().maxMemory();

             System.out.println("vmname="+vmname);

 

             System.out.println("totalM="+totalM/1024+"----maxM="+maxM/1024);

   }

}

__________________________________________________________________

got the output and actual memory:

Vmname=Java HotSpot(TM) 64-bit Server VM

totalM=59392------maxM=69312

Result: The actual memorys value is much smaller than the value that the case gives.

IMPT: We checked 32bits ubuntu, it looks fine. And solaris is fine too.
Reproduces every time. The value reported as totalMemory() is the memory committed for the heap, maxMemory() is the ressrved memory.
If I set -Xms60m I get 60293120 committed. That's 60M - 2.5M
