|
|
* 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.resume()</code> <BR>
|
||
|
|
* complies with its spec. <BR>
|
||
|
|
* <BR>
|
||
|
|
* The case for testing includes four ThreadGroup objects defined <BR>
|
||
|
|
* in a debuggee and their mirrors in a debugger. <BR>
|
||
|
|
* Parenthood relationships between the objects are as follows: <BR>
|
||
|
|
* threadGroups 2&3 are subgroups of threadGroup1 <BR>
|
||
|
|
* threadGroup4 is a subgroup of threadGroup3 <BR>
|
||
|
|
* The objects are created together with three threads, Thread 2,3,4, <BR>
|
||
|
|
* belonging to the corresponding subgroups. <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 the threads, <BR>
|
||
|
|
* informs the debugger of the threads creation, <BR>
|
||
|
|
* and is waiting for reply. <BR>
|
||
|
|
* Since the threads use the same locking object in their 'run' methods <BR>
|
||
|
|
* they are locked up until main thread leaves the synchronized block. <BR>
|
||
|
|
* Upon the receiption a message from the debuggee, <BR>
|
||
|
|
* the debugger gets mirrors of threadGroups and checks up that <BR>
|
||
|
|
* after suspending all the three threads: <BR>
|
||
|
|
* - group4.resume(); resumes only Thread4; <BR>
|
||
|
|
* - group3.resume(); resumes Thread3 and Thread4; <BR>
|
||
|
|
* - group2.resume(); resumes only Thread2; <BR>
|
||
|
|
* - group1.resume(); resumes Thread2, Thread3 and Thread4. <BR>
