* properly throws <i>IllegalArgumentException</i> - if the
* field is not valid for this object's class.<br>
* The debuggee part of the test contains two classes: the main one
* <i>setvalue002t</i> and the dummy one <i>DummyClass</i>. Each of
* them has the same set of static and instance fields.<br>
* The debugger part provokes the IllegalArgumentException trying to
* set value of:
* <li>an object reference to the debuggee's class <i>setvalue002t</i>
* and Field's value from an object reference to the debuggee's class
* <i>DummyClass</i>
* <li>an object reference to the debuggee's class <i>DummyClass</i>
* and Field's value from an object reference to the debuggee's class
