/**
* The test for the implementation of an object of the type <BR>
* ObjectReference. <BR>
* <BR>
* The test checks up that results of the method <BR>
* <code>com.sun.jdi.ObjectReference.hashCode()</code> <BR>
* complies with its specification. <BR>
* The case for testing incliudes two ObjectReference objects <BR>
* beloning to the same VM. <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.hashCode() == objRef2.hashCode() <BR>
* - objRef1.hashCode() != objRef3.hashCode() <BR>
