/**

|
* Debuggee's part contains a tested class (class <code>B</code>) and debugger exercises
|
|
* method <code>runIt()</code> of this class by the following steps: <br>
|
|
* 1. On <code>ClassPrepareEvent</code> of class <code>B</code>,
|
|
* <code>MethodExitRequest</code> is created and debugger waits
|
|
* <code>MethodExitEvent</code> for <code><clinit></code> to be shure the static
|
|
* members of class <code>B</code> have been initialized <br>
|
|
* 2. After getting <code>MethodExitEvent</code> for <code><clinit></code>, <br>
|
|
* - debugger creates <code>MethodEntryRequest</code> <br>
|
|
* - invokes the tested method (method <code>runIt</code>) by calling
|
|
* <code>com.sun.jdi.ClassType.invokeMethod()</code>. <br>
|
|
* This invoking occurs in special thread of debugger's part so that
|
|
* debugger can process the events of the target VM.
|
|
* 3. When getting <code>MethodEntryEvent</code> from the invoked method,
|
|
* debugger tries to pop current frame (with 0 index).
|
|
*
|
|
* The test passes when the above steps have been successfuly executed.
