Hi all,

I am working with the GC and I need a little help, maybe someone can
help me.
I have the following code:

import java.rem.RemObject;
import MyObject;

class Test {
 public static void main(String[] args) {
  MyObject obj = new MyObject();
  obj = null;

///////////// libraries/javalib/java/rem/RemObject.java
public class RemObject {
   public static void met1(Object obj) {
   static native void nmet1(Object obj);

//////////// libraries/clib/native/Remote.c
java_rem_RemObject_nmet1(struct Hjava_lang_Object* obj) {
 auxPtr = obj; // This is a global variable.

The GC reaches the memory pointed by auxPtr and marks it Black.
I suppose that this happens because I have a pointer to that piece of
memory in auxPtr, but I can't figure out how it is reached by the
In other words, I need to know if this memory is being used by the "user
Java program" (in this case, it is not), Could the Collector tell me

Thank you in advance.
