Maximum thread in java

Question

I have created a program to check max no of thread in java
public class Test extends Thread {
static int count;
public static void main (String [] args){
for(;;){
count++;
System.out.println(count);
new Test().start();
@Override
public void run() {
try {
Thread.sleep(100000000);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
First iteration -Xmx1024m ,max thread = 2011 > Second iteration -Xmx512m ,max thread = 3350 > third iteration -Xmx2m ,max thread = 5112
I have also tried with setting -Xss1m ,max thread = 1011, then I have set -Xss256k max thread 4900+
Can anyone suggest me
