 * <code>com.sun.jdi.ObjectReference.equals()</code>            <BR>

 * <BR>
 * The test works as follows.                                   <BR>
 * Upon launch, a debuggee infroms a debugger of creating       <BR>
 * tested objects.                                              <BR>
 * The debuggee gets two ObjectReference objRef1 and objRef2    <BR>
 * mirroring the same object in the debuggee, and               <BR>
 * ObjectReference objRef3 mirroring another object.            <BR>
 * Then it checks up that                                       <BR>
 * - objRef1.equals(objRef2) returns true and                   <BR>
 * - objRef1.equals(objRef3) returns false.                     <BR>
