* The test for the implementation of an object of the type <BR> |
|
39 |
* StackFrame. <BR> |
|
40 |
* <BR> |
|
41 |
* The test checks up that results of the method <BR> |
|
42 |
* <code>com.sun.jdi.StackFrame.thread()</code> <BR> |
|
43 |
* complies with its spec. <BR> |
|
44 |
* <BR> |
|
45 |
* After being started up, <BR> |
|
46 |
* a debuggee creates a 'lockingObject' for synchronizing threads, <BR> |
|
47 |
* enters a synchronized block in which it creates new thread, thread2, <BR> |
|
48 |
* informs a debugger of the thread2 creation, and is waiting for reply. <BR> |
|
49 |
* Since the thread2 uses the same locking object as main one <BR> |
|
50 |
* it is locked up until the main thread leaves the synchronized block. <BR> |
|
51 |
* Upon the receiption a message from the debuggee, the debugger <BR> |
|
52 |
* performs the following. <BR> |
|
53 |
* 1) After getting a thread2 suspended but before to resume it, <BR> |
|
54 |
* the name of the thread2 got with StackFrame.thread() is equal to <BR> |
|
55 |
* its name used for suspending the thread2. <BR> |
|
56 |
* Since the thread2 is not resumed yet, <BR> |
|
57 |
* InvalidStackFrameException must not be thrown. <BR> |
|
58 |
* 2) After resuming the thread2, the tested method is invoked <BR> |
|
59 |
* second time and InvalidStackFrameException must be thrown. <BR> |
