java.lang.reflect.Method.getModifiers() produces a wrong result

Name: dkC59003 Date: 08/20/99



When running JDK 1.2.2 VM method getModifiers() produces a wrong result
(see test source below): it does not include NATIVE flag. This does not
occur with JDK 1.2, 1.3beta1 and HotSpot VMs.

$ java -version
java version "1.2.2"
Classic VM (build JDK-1.2.2-W, native threads, symcjit)
$ java b4242912
Modifiers = 1
Method = public int java.lang.Object.hashCode()

Whereas for instance:

$ java -classic -version
java version "1.3beta"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3beta-N)
Classic VM (build 1.3beta-N, native threads, nojit)
$ java -classic b4242912
Modifiers = 257
Method = public native int java.lang.Object.hashCode()


----------------------------------------------------------- b4242912.java
import java.lang.reflect.*;

public class b4242912 {

    public static void main( String argv[] ) {
try {
Class c = Class.forName("java.util.List");
            Method m = Array.newInstance(c, 1).getClass().getMethod("hashCode",
                           new Class[]{});
            System.out.println("Modifiers = " + m.getModifiers());
            System.out.println("Method = " + m);
} catch (ClassNotFoundException e) {
} catch (NoSuchMethodException e) {}
    }
}
