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

* The test checks up that results of the method <BR>
* <code>com.sun.jdi.VirtualMachine.canGetBytecodes()</code> <BR>
* complies with its spec. <BR>
* <BR>
* The test works as follows. <BR>
* After being started up, a debuggee informs a debugger. <BR>
* Upon the receiption a message from the debuggee, the debugger <BR>
* - gets the Method mtd object <BR>
* mirroring the method "testedMethod" in the debuggee, <BR>
* - calls to the method VirtualMachine.canGetBytecodes() <BR>
* to get its returned value. <BR>
* Then if the value is true the debugger checks up that invoking <BR>
* the method Method.bytecodes() on the mtd doesn't throw <BR>
* UnsupportedOperationException. <BR>
* If the value is false the debugger checks up that invoking <BR>
* the method Method.bytecodes() on the mtd does throw <BR>
* UnsupportedOperationException. <BR>
