VM -oss flag does not work with jit enabled. The following
test overflows the stack by recursive method invocation. With
jit enabled the depth of recursion does not depend on
-oss stack size option. While this option works fine on 1.2beta3
or 1.2fcs with jit disabled.

Test example and VM diagnostics follow:

public class test {
    public static int r = 0;
    public static void m(){
       r++;
       m();
    }
    public static void main(String argv[]) {
       try {
          m();
       } catch ( StackOverflowError e) {
          System.out.println("Recursion depth: " + r);
       }
    }
}
