VM (versions 1.1.6-1.2FCS-D) with Symantec jit (Versions
3.00.053-3.00.063)
throws no NullPointerException when invoking equals() method with object

reference which is pointed to null.
This bug appears only with jit enabled on win32 port. It is possibly
connected with for() statement optimization. Without for() all works
fine.

An example and VM diagnostics follow:
-----------------------------------------------------------------
novo35% cat clss14702.java
public class clss14702 {
    static int ML = 1;
    public static void main(String argv[]) {
        clss14702 test = null;
        for (int i = 0; i < ML; i++)
            try {
                if ( test.equals(null) ) {
                    System.out.println("Error! NullPointerException
should be thrown.");
                }
                System.out.println("Error! No exception.");
                System.exit(2);
            } catch (Exception e) {
                if ( ! NullPointerException.class.isInstance(e) ) {
                    System.out.println("Error! Exception: " + e);
                    System.exit(2);
                }
            }
       System.out.println("Passed");
    }
}
