/**
* The test for the implementation of an object of the type <BR>

* <BR>
* The test checks up that results of the method <BR>
* <code>com.sun.jdi.VirtualMachine.allClasses()</code> <BR>
* complies with its spec. <BR>
* <BR>
* The test check up that new class and interface types <BR>
* are in returned List only after corresponding objects<BR>
* have been created within the debuggee. <BR>
* The sequence of the cases for testing is as follows: <BR>
* <BR>
* Objects# == 0, Classes# == 0, Interfaces# == 0 <BR>
* hence, the returned List must contain no mirrors of <BR>
* tested reference types; <BR>
* Objects# == 1, Classes# == 1, Interfaces# == 0 <BR>
* the returned list must contain only one expected <BR>
* object mirroring a tested Class type; <BR>
* Objects# == 2, Classes# == 2, Interfaces# == 1 <BR>
* the returned list must contain three expected objects<BR>
* mirroring two Class and one Interface types; <BR>
* Objects# == 3, Classes# == 2, Interfaces# == 1, <BR>
* the returned list must contain three expected objects<BR>
* mirroring two Class and one Interface types; <BR>
* repetirion of previous check after one more object <BR>
* has been created; <BR>
* Objects# == 4, Classes# == 3, Interfaces# == 1, <BR>
* the returned list must contain four expected objects <BR>
* mirroring three Class and one Interface types; <BR>
