|
* The test for the implementation of an object of the type <BR>
|
|
* ThreadGroupReference. <BR>
|
|
* <BR>
|
|
* The test checks up that results of the method <BR>
|
|
* <code>com.sun.jdi.ThreadGroupReference.parent()</code> <BR>
|
|
* complies with its spec. <BR>
|
|
* <BR>
|
|
* The case for testing includes four ThreadGroup objects defined <BR>
|
|
* in two debuggee's classes and in an external class, <BR>
|
|
* and their mirrors in a debugger. <BR>
|
|
* Parenthood relationships between the objects are as follows: <BR>
|
|
* mainParent -> mainthreadGroup -> thread2Group1 -> thread2Group2 <BR>
|
|
* The objects are created together with two debuggee's threads, <BR>
|
|
* mainthread and a thread2. <BR>
|
|
* The test works as follows. After being started up, <BR> <BR>
|
|
* the debuggee creates a 'lockingObject' for synchronizing threads, <BR>
|
|
* enters a synchronized block in which it creates new thread, <BR>
|
|
* the thread2, informs a debugger of the thread2 creation, <BR>
|
|
* and is waiting for reply. <BR>
|
|
* Since the thread2 uses the same locking object in its 'run' method <BR>
|
|
* it is locked up until main thread leaves the synchronized block. <BR>
|
|
* Upon the receiption a message from the debuggee, <BR>
|
|
* the debugger gets the mirrors of all the ThreadGroup objects, <BR>
|
|
* and checks up the above mentioned parenthood relationships. <BR>
