|
|
45 |
* The cases for testing are as follows. <BR>
|
|
46 |
* After being started up, <BR>
|
|
47 |
* a debuggee creates a 'lockingObject' for synchronizing threads, <BR>
|
|
48 |
* enters a synchronized block in which it creates new thread, thread2, <BR>
|
|
49 |
* informs a debugger of the thread2 creation, and is waiting for reply.<BR>
|
|
50 |
* Since the thread2 uses the same locking object in its 'run' method <BR>
|
|
51 |
* it is locked up until main thread leaves the synchronized block. <BR>
|
|
52 |
* Upon the receiption a message from the debuggee, the debugger <BR>
|
|
53 |
* - sets up a breakpoint within thread2's 'run' method; <BR>
|
|
54 |
* - forces main thread to leave the synchronized block in order to <BR>
|
|
55 |
* unlock the thread2 to get it suspended at the breakpoint. <BR>
|
|
56 |
* Then the debugger performs a number of checking calls to <BR>
|
|
57 |
* thread2.frames(index,lenght) with the following arguments: <BR>
|
|
58 |
* <BR>
|
|
59 |
* start < 0 (-1) <BR>
|
|
60 |
* lenght < -1 (-2) <BR>
|
|
61 |
* lenght == 0 <BR>
|

62 |
